7. A particular task exposes the operator to alpha radiation at an average dose of 200 μGy each time the task is performed. If the company needs the task performed once per day over a 260-day working year and the maximum occupational dose limit is 20mSv per year, how many staff does the company need to assign to the task?

Solution Summary

Assuming that people do not have any protection, we can say that 1Gy is fully absorbed by a person, which means that it is equivalent to 1 Sv.

Solution Preview

This is very straightforward. First of all Gy stands for grey: 1Gy = J/kg, and Sv stands for sievert also 1J/kg, it measures the absorbtion of the radiation. Assuming that ...
