Radiation includes High-energy electromagnetic waves (x-rays, gamma rays) Particles (alpha particles, beta particles, neutrons) Alpha particles are energetic helium nuclei emitted by some radionuclides with high atomic numbers (eg, plutonium, radium, uranium); they cannot penetrate skin beyond a shallow depth (< 0.1 mm). Beta particles are high-energy electrons that are emitted from the nuclei of unstable atoms (eg, cesium-137, iodine-131). These particles can penetrate more deeply into skin (1 to 2 cm) and cause both epithelial and subepithelial damage. Neutrons are electrically neutral particles emitted by a few radionuclides (eg, californium-252) and produced in nuclear fission reactions (eg, in nuclear reactors); their depth of tissue penetration varies from a few millimeters to several tens of centimeters, depending on their energy. They collide with the nuclei of stable atoms, resulting in emission of energetic protons, alpha and beta particles, and gamma radiation. Gamma radiation and x-rays are electromagnetic radiation (ie, photons) of very short wavelength that can penetrate deeply into tissue (many centimeters). While some photons deposit all their energy in the body, other photons of the same energy may only deposit a fraction of their energy and others may pass completely through the body without interacting. Because of these characteristics, alpha and beta particles cause the most damage when the radioactive atoms that emit them are within the body (internal contamination) or, in the case of beta-emitters, directly on the body; only tissue in close proximity to the radionuclide is affected. Gamma rays and x-rays can cause damage distant from their source and are typically responsible for acute radiation syndromes (ARS—see Radiation Exposure and Contamination : Acute radiation syndromes (ARS)).

Radiation injury is damage to tissues caused by exposure to ionizing radiation. Large doses of ionizing radiation can cause acute illness by reducing the production of blood cells and damaging the digestive tract. A very large dose of ionizing radiation can also damage the heart and blood vessels (cardiovascular system), brain, and skin. Radiation injury due to large and very large doses is referred to as a tissue reaction. The dose needed to cause visible tissue injury varies with tissue type. Ionizing radiation can increase the risk of cancer. Radiation exposure of sperm and egg cells carries little increased risk of genetic defects in offspring. Doctors remove as much external and internal (material that is inhaled or ingested) radioactive material as possible and treat symptoms and complications of radiation injury. In general, ionizing radiation refers to high-energy electromagnetic waves (x-rays and gamma rays) and particles (alpha particles, beta particles, and neutrons) that are capable of stripping electrons from atoms (ionization). Ionization changes the chemistry of affected atoms and any molecules containing those atoms. By changing molecules in the highly ordered environment of the cell, ionizing radiation can disrupt and damage cells. Cellular damage can cause illness, increase the risk of developing cancer, or both.

How to Undergo a Lung Biopsy|mesothelioma lung cancer A lung biopsy can sound like a scary operation, but it is a fairly minimally invasive procedure in most cases. Consult with your doctor about your symptoms, your overall health (especially about any medications you are currently taking), and follow all pre-op instructions. Ask a friend to drive you home after the biopsy. 1 Record your symptoms. If you think you may have a problem with your lungs, you should write down what symptoms you are experiencing. Keep a journal over a period of several days or weeks so that you can show your doctor a detailed account of what you’ve been feeling lately. This will help your doctor make an informed decision about whether or not you need a lung biopsy. Keep track of things like difficulty breathing, localized pain, shortness of breath, fever/chills, and coughing up blood. There are also online symptom trackers and apps for your phone that you can use to record your symptoms and show to your doctor later 2 Consult with your doctor. Talk to your doctor about any concerns you might have about your overall health, or your lungs specifically. Bring your symptom records and discuss them with your doctor.[2] Your doctor may ask you to do some preliminary tests before deciding that a biopsy is necessary. This could include chest X-rays, CT scans, an MRI, chest ultrasound, bronchography, chest fluoroscopy, or a positron emission tomography (PET) scan. 3 Discuss your current medical conditions with your doctor. In order to determine if any extra precautions need to be taken for a lung biopsy, you’ll need to inform your doctor about any preexisting medical conditions you may have. This especially includes things like pregnancy, diabetes, allergies, and any medicines you may be currently taking (especially blood thinners). Remember to also give your doctor a comprehensive medical history. 4 Consider your overall health. As with any medical procedure, there are some risks involved wi

How to Screen for Lung Cancer|cancer screening center Lung cancer is the leading cause of cancer deaths among both genders in the U.S., claiming more lives than colon, prostate, ovarian and breast cancer combined.[1] People at the greatest risk for lung cancer include smokers and those who work with or around toxic chemicals, gases and irritating particles. Screening for lung cancer is important because it's much easier to treat in the early stages before spreading or metastasizing to other parts of the body. You can sort of screen / monitor yourself by understanding common symptoms, but periodically seeing your doctor for chest x-rays, sputum samples and/or CT scans is the best strategy. 1 Remember that early symptoms can be mild and vague. One of the reasons that lung cancer is so deadly is that the disease doesn't often cause noticeable symptoms during the early stages.[2] Furthermore, the mild symptoms of early stage lung cancer are often mistaken for a cold, bout of the flu, bronchitis or asthma. Common early signs of lung cancer (and most upper respiratory infections) include a mild, persistent cough, shortness of breath, fatigue, and weight loss. Signs and symptoms of lung cancer usually become noticeable once the disease is advanced, which is why it's such as deadly disease. The common cold, flu and bronchitis are viral infections that typically fade away two to three weeks, so if your symptoms persist, schedule an appointment with your doctor. 2 Be suspicious of a new cough that doesn't go away. One of the telltale symptoms of lung cancer is the development of a persistent cough that's either completely new or noticeably different than the typical dry, hacking smoker's cough.[3] In contrast to the dry and unproductive cough common with smokers, coughing up foul-smelling phlegm and even blood on occasion is not unusual with the mid-stages of lung cancer. Due to the constant coughing and slow destruction of tissue in the lungs from lung cancer, chest pain

Radiation exposure may be internal or external, and can be acquired through various exposure pathways. Internal exposure to ionizing radiation occurs when a radionuclide is inhaled, ingested or otherwise enters into the bloodstream (for example, by injection or through wounds). Internal exposure stops when the radionuclide is eliminated from the body, either spontaneously (such as through excreta) or as a result of a treatment. External exposure may occur when airborne radioactive material (such as dust, liquid, or aerosols) is deposited on skin or clothes. This type of radioactive material can often be removed from the body by simply washing. Exposure to ionizing radiation can also result from irradiation from an external source, such as medical radiation exposure from X-rays. External irradiation stops when the radiation source is shielded or when the person moves outside the radiation field. People can be exposed to ionizing radiation under different circumstances, at home or in public places (public exposures), at their workplaces (occupational exposures), or in a medical setting (as are patients, caregivers, and volunteers). Exposure to ionizing radiation can be classified into 3 exposure situations. The first, planned exposure situations, result from the deliberate introduction and operation of radiation sources with specific purposes, as is the case with the medical use of radiation for diagnosis or treatment of patients, or the use of radiation in industry or research. The second type of situation, existing exposures, is where exposure to radiation already exists, and a decision on control must be taken – for example, exposure to radon in homes or workplaces or exposure to natural background radiation from the environment. The last type, emergency exposure situations, result from unexpected events requiring prompt response such as nuclear accidents or malicious acts.

how common is skin cancer in children |skin cancer mortality Children have a small risk of skin cancer if they are not protected, but burns in childhood can have major repercussions when they reach adulthood, is these burns greatly increases their chances of skin cancer, including melanoma.” (the risk of melanoma is likely increased with even less than 6 severe sunburns). Recognizing the seriousness of skin cancer in children is one of the steps in protecting them. Apply sunscreen, cover exposed skin with clothing, and diagnose potential skin cancer for optimal skin protection. 1 Cover up sun-exposed areas. Ensure that your child is covered up when exposed to the sun for long periods. Even while at the beach, you should have your child wear a t-shirt while out of the water. Consider a one-piece swimsuit for girls and/or a rash guard or swim shirt for girls and boys. [12] You can also encourage your child to take cover under an umbrella or shaded area. 2 Cover your child’s head. Make a habit of having your child wear a hat when outdoors to avoid skin cancer risks. A hat with a brim that covers the face and neck is ideal. If you are consistent, your child will adjust to wearing a hat outside when it is sunny. [13] Choose a hat with a brim that’s at least three inches all the way around. 3 Opt for sunglasses for your children. Just as adults should protect their eyes from the sun, children should too. Again, if consistent, children should not have a problem wearing sunglasses on sunny days. [15] Choose sunglasses that protect from UVA and UVB rays. The sunglasses should fit snugly on your child’s face

How to Clean a medications to hold before cardiac cath|cardiac Catheterization Site Cardiac catheterization is a common medical procedure which enables your doctor to examine your heart. A small tube is inserted through a blood vessel in your leg or arm and moved through your body until it reaches your heart. The catheter may be used to check the blood pressure in your heart, put contrast dye into your heart to facilitate taking X-rays, take blood samples, biopsy your heart, or check for structural problems with the chambers or valves. Because it is an invasive procedure, minimizing infection risk before and after the procedure is very important 1 Avoid people who are sick. If you are sick, even with a minor illness like a cold or flu, this burdens your immune system and makes it easier for you to develop complications. If you wake up the morning of your procedure with a fever, cough, drippy nose, or any other symptoms, notify your doctor immediately.[12] Wash your hands after you shake hands with people and before you eat. This will reduce the likelihood that you expose yourself to pathogens carried by others. Don’t go near, hug, or shake hands with people who have the flu or a cold. Avoid being in small confined spaces with lots of people. These are excellent opportunities for pathogen exchange. This may mean not taking public transportation such as the bus or subway. 2 Boost your immune system by managing stress. Stress causes hormonal and physiological changes in your body which, over time, can weaken your immune system. By easing stress and anxiety before the procedure, you can help ensure that your immune system will remain strong. You can reduce stress by: Learning as much as possible about your procedure. Your doctor and the hospital can provide you with information. Many hospitals even have booklets of information that they provide and make freely available online. Ask your doctor or hospital if such information is available. If so, it will help you under

How to Find the Cause of Aortic Regurgitation|bicuspid aortic valve chest pain Aortic regurgitation is when there is damage to the aortic valve, causing blood to leak backwards from the aorta (the body's largest blood vessel) back into the heart after each heartbeat. There are a number of things that can cause aortic regurgitation, including infection, trauma, rheumatic heart disease, aneurysm, and congenital and hereditary causes. The main way to determine the cause of aortic regurgitation is through cardiac imaging. Other medical tests may also be ordered to confirm the underlying cause of aortic regurgitation as well as assess overall cardiac health. 1 Receive a transthoracic echocardiogram. A transthoracic echocardiogram (commonly called an "echo") is usually the first specific investigation to look at the function of the aortic valve. It uses ultrasound waves to create an image of the heart as it functions in real time. It shows each heartbeat, and can assess blood flow through the various chambers of the heart with each heartbeat.[8] An echo can also be used to determine the underlying cause of aortic regurgitation. 2 Have a transesophageal echocardiogram. If a transthoracic echocardiogram is insufficient to determine the underlying cause of aortic regurgitation, the next step is to proceed to a transesophageal echocardiogram. This is when, rather than having the test performed from outside your chest, an ultrasound probe is instead inserted down your esophagus to provide a more close-up and detailed view of your heart, 3 Obtain other diagnostic tests as needed. Depending upon what is suspected as the underlying cause of aortic regurgitation, additional investigations may be ordered to provide more information. For instance, if an infection of the heart valve is suspected, blood tests and a blood culture will likely be ordered to test for the presence of bacteria. If trauma is suspected, a chest x-ray or CT scan will likely be needed to evaluate for injury

Stopping exposure to lead Sometimes whole-bowel irrigation Sometimes chelation therapy and mineral supplements Treatment consists of stopping exposure to lead and removing accumulated lead from the body. If an abdominal x-ray shows lead chips, a special solution of polyethylene glycol is given by mouth or through a stomach tube to wash the contents of the stomach and intestines (a process called whole-bowel irrigation). Doctors remove lead from the body by giving drugs that bind with the lead (chelation therapy), allowing it to pass into the urine. All drugs that remove lead work slowly and can cause serious side effects. Succimer is one drug used in chelation therapy. People with mild lead poisoning are given succimer by mouth. People with more serious lead poisoning are treated in the hospital with injections of chelating drugs, such as dimercaprol, succimer, and edetate calcium disodium. Because chelating drugs also can remove beneficial minerals, such as zinc, copper, and iron, from the body, the person often is given supplements of these minerals. Even after treatment, many children with encephalopathy develop some degree of permanent brain damage. Kidney damage is also sometimes permanent.
