For those who are occupationally exposed to ionizing radiation above the natural background level, it is important to limit their exposure dosage as much as possible in order to minimize potential harmful effects of ionizing radiation. Which of the below represent one of the methods that are used in practice to limit radiation doses? 0 "Type": Use the safest type of radiation available. 0 "Time": Reduce amount of time spent near the radiation source. 0 "Delegation": Employ lower-paid personnel to spend time near the radiation source instead. 0 "PPE": Use personal protective equipment such as safety goggles and masks to limit radiation exposure. Nuclear radioactivity produces three main types of radiation, at, ,3, and 1' radiation. Each type of radiation has different penetrating power and requires different amount of minimal shielding material. Which of the below correctly.r rank (1, ,3, and 1* radiation in the order from requiring "least'I shielding material to "most".P D LEAST: or radiation - '1' radiation ,3 radiation :MUST D LEAST: ,6 radiation "f radiation (I radiation :MUST C} LEAST: 1' radiation - ,3 radiation (I radiation :MUST C} LEAST: Cr radiation - ,3 radiation - 1' radiation :MUST What does time dilation effect in special relativity.r predict? Q It predicts that time goes slower when you are having fun. 0 It predicts that moving clocks run slower, when compared to clocks stationary.r in the observer's reference frame. 0 It predicts that stationary clocks slow down, when compared to clocks that are kept in constant motion. 0 It predicts that presence of ionizing radiation causes clocks to run slower
