Answer 5

Highest point

Question 6

Answer 6

Back away until the PRD displays a value below 2 mRem/hr
Set up an exclusion zone

Question 7

Answer 7

It is safe to operate in that zone for no more than 3 minutes.

Question 8

If MORE than 10 feet from the source and the PRD reading is 2 mRem/hr. or higher (HIGH GAMMA), what 3 steps should be taken?
