1. When the operator pushes the check source pushbutton, the radiation monitor will respond by (1).
2. During the check source, actuation of interlocks (2) expected.
A. (1) a rise in counts until the check source pushbutton is released (2) are
B. (1) a rise in counts until the check source pushbutton is released (2) are NOT
C. (1) a rise in counts then a return to original reading (2) are NOT
D. (1) a rise in counts then a return to original reading (2) are
▶ Show Answer & Explanation
✓ C. Correct. When a check source is performed on this radiation monitor, the counts will rise then return to its previous reading. During check source it is not expected for interlocks to actuate.
✗ A. Incorrect. Plausible because other radiation monitors do perform like this. Incorrect in that this radiation monitor check source the counts rise then fall and interlocks are not expected during check source.
✗ B. Incorrect. Plausible because other radiation monitors do perform like this. Incorrect in that this radiation monitor check source the counts rise then fall and interlocks are not expected during check source.
✗ D. Incorrect. Plausible because some other radiation monitors interlocks could occur during check source.
