Environmental Area Monitoring; Checking For Surface Contamination - International Medcom Inspector Operating Manual

Environmental Area Monitoring

You can keep the Inspector in CPM or mR/hr mode whenever you want to
monitor the ambient radiation, and look at it from time to time to check for
elevated readings.
If you suspect an increase in ambient radiation, use the timer and take a five or
ten minute count, and compare the average to your average background
count. If you suspect an increase that is too small to detect with a short timed
reading, you can take a longer count (for example 6, 12, or 24 hours).

Checking for Surface Contamination

To check a surface, hold the Inspector with the alpha window facing and close
to the surface. If you want to find out if a surface is slightly radioactive, place
the Inspector next to it and take a timed count or a longer accumulated count.
CAUTION: Never touch the Inspector to a surface that may be contaminated.
You may contaminate the instrument. The rubber strips on the back can be
replaced if they become contaminated. Replacement strips are supplied with
the Inspector.
