Uranium (fuel source)
Iridium (radiographic source)
Radium (flourescent source)
Control of exposure to radiation is driven by 3 factors- time, distance, and shielding. Radiation is subject to the "inverse square law- doubling distance reduces exposure by the inverse square- so a little distance (long handled tongs) reduces exposure a LOT.
1) Emission (the source gives out the radiation) 2) Journey (the radiation travels through the medium (which could be any substance or a vacuum) 3) Detection (the radiation is absorbed by another object
The dicentric chromosome assay is a blood test that provides an accurate estimate of radiation dose. It detects and quantifies chromosome damage caused by radiation exposure and is used in cases of suspected or accidental radiation exposure.
The three types of radiation with short wavelength and high frequency are X-rays, gamma rays, and ultraviolet (UV) radiation. These forms of radiation have energetic photons and can have harmful effects on living organisms if exposure is not controlled.
Our eyes detect three types of waves: visible light, which allows us to see colors and shapes; infrared radiation, which we sense as heat; and ultraviolet radiation, which is invisible to the naked eye but can cause damage to our eyes and skin with prolonged exposure.
Radiation sickness varies depending upon duration of exposure, whether it was an internal or external exposure, and the dosage of radiation.
A single exposure to high-energy radiation exposure to high levels of fallout repaeted exposures to both high-energy radiation and high levels of fallout

3 reasons people get exposed to radiation poisoning is: Accidental, intentional and without a person's knowledge - mysterious unknown source. The methods of exposure: medical, criminal actions, intentional murder by exposing a person to oral intake of it, inhalation or total body exposure to the radioactive source. Too much exposure to radiation can result in death therefore all businesses, military forces and other places rigorously guard against exposure or the poisoning by radiation.

The three key factors important in protecting individuals from radiation are time, distance, and shielding. Reducing the time spent near a radiation source decreases exposure, while increasing the distance from the source significantly lowers radiation intensity due to the inverse square law. Additionally, using appropriate shielding materials can effectively absorb or block radiation, further minimizing exposure risks. Together, these factors help ensure safety in environments where radiation is present.
LD50/30 radiation refers to the dose of radiation required to kill (LD=Lethal Dose) 50% of the test cohort within 30 days. Its normally specified for a particular species, rats, rabbits etc and is thought to be about 3-4 Sieverts in humans. The wikipedia article "Radiation Poisoning" has a table of effects of increasing radiation on humans. Note that at 3-4 Sv there are no skin effects if it is whole body exposure. If it is localised exposure then there will be radiation burns followed by erythema.
The cost which are associated with the inventory are: 1) Procurement cact 2) Ordering cost 3) Carrying cost
X-ray wise? Collimation, Lead shield, use adequate kVp and mAs
There are several sources of natural or background radiation for people.First, there are naturally occurring radioactive elements in the crust of the earth which have been present since the earth's formation. These can irradiate people in several ways.They can irradiate people externally because the soil and rocks all around us (and some building materials such as concrete and brick) act as radiation sources.Plants and animals that we use for food take in the radioactive elements and we ingest them along with our food.Some of the radioactivity is present in the air and we inhale it along with the air.Second, there are radioactive elements which are produced by interactions of cosmic rays with the atmosphere, the best known being carbon-14 and hydrogen-3 (or tritium). These can irradiate us in much the same ways as the elements discussed above.Third, we are constantly irradiated by cosmic rays.
