Radiation State Card Exam correctly answered 2023

Radiation State Card Exam correctly answered 2023A curie is a unit of: Activity The radiation dose may be reduced by: Moving farther from the source What must the operator do before each survey? Perform a radiation survey Gamma rays have a shorter wavelength than light and heat; therefore they are: Very penetrating What living person is most sensitive to radiation? An unborn child All operators should be familiar with their operating and emergency manual and if an emergency occurs, the most important step to take is: Stop and think before acting The most common survey used instrument used in isotope radiography is: Geiger-Mueller (GM) Chronic is relatively a low level of exposure received over a long period of time True or False? True A TVL (Tenth Value Layer) is the amount of shielding sufficient to: Attenuate a beam of radiation to one-tenth its initial value In the event that an exposure device is stolen, the operator should immediately: Notify the RSQ/RPO In the event of a road accident that involves an exposure device where the survey meter is damaged, the operator should immediately: Assume that the source is fully exposed and restrict and post the area People and metal objects that become exposed to sealed radiography sources emitting gamma rays become radioactive true or false? False If the sealed source is damaged and it is suspected that it is leaking, the operator should immediately: Cease all radiographic operations and restrict the area The sievert (Sv) replaces the rem and on Sievert equals: 100 rem All radiation injuries result primarily from radiation induced chemical changes in one or more of the complex molecules present in living cells True or False? True The reason of the use of 2 lithium fluoride chips (thin and thick) in the thermoluminescent dosimeter is: Measurement of skin and body dose. Effects of radiation that are evident in the individual: Somatic effects
