This is a translation of Holy Quran (Koran) in English. Koran is a sacred book that contains the words of God. It was revealed in verses overtime to Prophet Muhammad by Angel Gabriel. It is the last of the books that was sent to the last of the prophets, Prophet Muhammad (PBUH) to mankind.
The amount of radiation is measured in several different units. The roentgen (R) is a measure of the ionizing ability of radiation in air and is commonly used to express the intensity of exposure to radiation. How much radiation people are exposed to and how much is deposited in their body may be very different. The gray (Gy) and sievert (Sv) are measures of the dose of radiation, which is the amount of radiation deposited in matter, and are the units used to measure dose in humans after exposure to radiation. The Gy and Sv are similar, except the Sv takes into account the effectiveness of different types of radiation to cause damage and the sensitivity of different tissues in the body to radiation. Low dose levels are measured in mGy (1 mGy = 1/1000Gy) and mSv (1 mSv = 1/1000Sv).
Contamination vs. irradiation
An individual's radiation dose can be increased in two ways, contamination and irradiation. Many of the most significant radiation accidents have exposed people to both.
Contamination is contact with and retention of radioactive material, usually as a dust or liquid. External contamination is that on skin or clothing, from which some can fall or be rubbed off, contaminating other people and objects. Internal contamination is radioactive material deposited within the body, which it may enter by ingestion, inhalation, or through breaks in the skin. Once in the body, radioactive material may be transported to various sites, such as the bone marrow, where it continues to emit radiation, increasing the dose, until it is removed or emits all its energy (decays). Internal contamination is more difficult to remove than external contamination.
The lymphatic system is made up of lymph capillaries, vessels, and nodes, the spleen, thymus, tonsils, Peyer’s Patches, and lymphocytes (white blood cells). Red bone marrow is also a part of the lymphatic system. We have hundreds of lymph nodes. Lymph nodes can be found all around the lungs and heart, in the gut, in the armpits and groin, and pretty much all over the body.
Blood pressure causes plasma liquid to leak into tissues, and this pressure causes excess fluid in those tissues to move into the lymph capillaries. As this fluid leaves the cells, it takes cellular waste products and used proteins with it. The lymphatic capillaries pick up approximately 20% of the fluid that was delivered to the interstitial space. The venous system picks up about 80% of the fluid in the interstitial space. The unique structure of the lymphatic capillaries permits interstitial fluid to flow into them but not out.
Blood pressure, temperature, activity of muscle and joints, diaphragmatic breathing, and pulsation of adjacent arteries all cause lymph to move up to the subclavian veins at the base of the neck. Valves and pressure keep lymph moving in the right direction. Along the way, the fluid is interrupted by lymph nodes that filter dust, cancer cells, pathogens, and other unwanted matter. Lymph nodes also produce lymphocytes (white blood cells). The spleen, tonsils, and red bone marrow help produce lymphocytes as well.
The spleen, which is about the size of our fist, is the largest lymphatic organ. It is similar in structure to a lymph node, but it filters blood, not lymph. The spleen contains two main types of tissue, white pulp and red pulp. White pulp is lymphatic tissue containing white blood cells – B and T cells. T cells attack pathogens (such as bacteria and viruses) while B cells make antibodies that fight infections. Red pulp tissue removes old and damaged red blood cells and stores platelets. It also produces red blood cells in unborn babies and when certain disease
Commercially available kits should be used to test household paint (except in houses built after 1978), ceramics made outside the United States, and water supplies for lead content. Measures that reduce the risk of household poisoning include regular cleaning, such as
Washing of children’s toys and pacifiers
Cleaning of household surfaces
Dusting affected windowsills weekly with a damp cloth
Chipped leaded paint should be repaired. Larger renovation projects to remove leaded paint can release large quantities of lead into the house and should be done professionally. Commercially available faucet filters can remove most lead from drinking water.
Adults exposed to lead dust at work should
Use appropriate personal protective equipment
Change their clothing and shoes before going home
Shower before going to bed
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.

Radioactive contamination and radiation exposure could occur if radioactive materials are released into the environment as the result of an accident, an event in nature, or an act of terrorism. Such a release could expose people and contaminate their surroundings and personal property.
Internal contamination occurs when people swallow or breathe in radioactive materials, or when radioactive materials enter the body through an open wound or are absorbed through the skin. Some types of radioactive materials stay in the body and are deposited in different body organs. Other types are eliminated from the body in blood, sweat, urine, and feces.
External contamination occurs when radioactive material, in the form of dust, powder, or liquid, comes into contact with a person's skin, hair, or clothing. In other words, the contact is external to a person's body. People who are externally contaminated can become internally contaminated if radioactive material gets into their bodies.
Radioactive contamination occurs when radioactive material is deposited on or in an object or a person. Radioactive materials released into the environment can cause air, water, surfaces, soil, plants, buildings, people, or animals to become contaminated. A contaminated person has radioactive materials on or inside their body.
Radioactive materials give off a form of energy that travels in waves or particles. This energy is called radiation. When a person is exposed to radiation, the energy penetrates the body. For example, when a person has an x-ray, he or she is exposed to radiation.
