Lead is a cumulative toxicant that affects multiple body systems and is particularly harmful to young children. Lead in the body is distributed to the brain, liver, kidney and bones. It is stored in the teeth and bones, where it accumulates over time. Human exposure is usually assessed through the measurement of lead in blood. Lead in bone is released into blood during pregnancy and becomes a source of exposure to the developing fetus. There is no known level of lead exposure that is considered safe. Lead poisoning is entirely preventable. Lead is a naturally occurring toxic metal found in the Earth’s crust. Its widespread use has resulted in extensive environmental contamination, human exposure and significant public health problems in many parts of the world. Important sources of environmental contamination include mining, smelting, manufacturing and recycling activities, and, in some countries, the continued use of leaded paint, leaded gasoline, and leaded aviation fuel. More than three quarters of global lead consumption is for the manufacture of lead-acid batteries for motor vehicles. Lead is, however, also used in many other products, for example pigments, paints, solder, stained glass, lead crystal glassware, ammunition, ceramic glazes, jewellery, toys and in some cosmetics and traditional medicines. Drinking water delivered through lead pipes or pipes joined with lead solder may contain lead. Much of the lead in global commerce is now obtained from recycling. Young children are particularly vulnerable to the toxic effects of lead and can suffer profound and permanent adverse health effects, particularly affecting the development of the brain and nervous system. Lead also causes long-term harm in adults, including increased risk of high blood pressure and kidney damage. Exposure of pregnant women to high levels of lead can cause miscarriage, stillbirth, premature birth and low birth weight, as well as minor malformations.

Medical diagnostic procedures used to define and diagnose medical conditions are currently the greatest manmade source of ionizing radiation exposure to the general population. However, even these sources are generally quite limited compared to the general background radiation on Earth. The risks and benefits of radiation exposure due to medical imaging and other sources must be clearly defined for clinicians and their patients. This article is a general overview for the medical practitioner, who should understand the fundamentals of medical ionizing radiation and the general associated risks. This article also acquaints the practitioner with relative doses of common radiographic procedures as well as natural background radiation. The use of ionizing radiation in medicine began with the discovery of x-rays by Roentgen in 1895. Ionizing radiation is the portion of the electromagnetic spectrum with sufficient energy to pass through matter and physically dislodge orbital electrons to form ions. These ions, in turn, can produce biological changes when introduced into tissue. Ionizing radiation can exist in 2 forms: as an electromagnetic wave, such as an x-ray or gamma ray, or as a particle, in the form of an alpha or beta particle, neutron, or proton. X-rays are machine-generated, whereas gamma rays are electromagnetic waves that are emitted from the nucleus of an unstable atom. Different forms of ionizing radiation have differing abilities to generate biologic damage. The order of ionization effect of these forms can be found in Table 1 below. A clear understanding of the measurement units of radiation and radioactivity is required to better communicate with colleagues or patients. Different units are used to describe radioactivity by energy (erg), decay activity rate (curie [Ci] or becquerel [Bq]), effect in air (roentgen [R]), ability to be absorbed (radiation-absorbed dose [rad] or gray [Gy]), or biologic effect (roentgen equivalent man [rem] or sievert [Sv]).

Review: Achieving first-person-view in the film, regardless of how so many people panic and label it as a bad movie before giving into it, It’s not a valid review or opinion at best. To turn a blind eye where the performance makes its purpose able to shine some moments with great outcomes, will otherwise make these movies basically fell neglected as they really try to pull the watcher into it. That is precisely how detached from the entertainment purpose and originality are most of the movies coming out recently. Will Porter, is a researcher pilot employed by a shady corporation to intercede when an investigation and test of Alterplex energy source goes disastrously inappropriate for the smooth promised work. longing to secure his own family he consents to go up against a rebel mission with a procedure that is never simplified throughout the movie. Smit draws the structure of a very interesting world, with plenty points of interest and futuristic gadgets. Law executioner robots, police drone planes, trucks, and tanks don’t make Will´s life and work easier, especially after he finds that he is eight kilometers away from the mission objective. Kill Switch is not constrained to its story that really doesn't uncover much about the current state of the world they live. After Will acknowledges that Alterplex Energy Corporation has made a parallel world, The Echo, things went even worse after he finds himself inside it. The goal to live this movie through his own vision is at times fulfilling. Movies have been continually developing ways to get the FPS style the vitality it needs to break the current barriers of an old mentality of movie goers behaving as distant watchers. These movies want you inside the action like any other FPS video game. It never neglects to express what makes these different motion pictures intriguing, while the sci-fi and special effects are convincing enough.
