Question

In radiation safety, the control booth should be located in an area that ensures the radiation has been scattered how many times before entering the booth?

a) Once
b) Twice
c) Thrice
d) Four times

Answer 1

In radiation safety, the control booth should be positioned such that radiation is scattered at least twice before entering, as part of broader radiation protection measures.

Step-by-step explanation:

In radiation safety, one of the key demands for the location of a control booth is that it ensures the radiation has been scattered at least two times before it can enter the booth. This is a component of the broader radiation protection principles which also include minimizing the time spent in a radiation environment to reduce exposure, maintaining as much distance from the radiation source as feasible due to the inverse square law, and using adequate shielding between oneself and the radiation source to further lessen exposure.
