2.2.5.6 ALPHA/BETA PROBE, ABP100
1. With the survey meter turned OFF, connect the probe cable to the 7-pin
connector on the probe and the other end of the cable to the ADM300 7-pin
connector.
2. Turn the survey meter power ON. The unit displays "Please Wait" then
"ALPHA-BETA PROBE" and units of measurement appear. The unit
automatically begins to measure Alpha and Beta radiation.
Note: If the unit does not indicate probe is attached, refer to Chapter 3, Operator
Maintenance, for trouble shooting procedures.
3. To monitor Alpha and Beta radiation remove the protective cover, place the
probe window toward the contamination source.
4. To select between the available alpha and beta rate measurement units use the
(↑) button.
Refer to the alpha / beta probe functional flow diagram for available modes.
5. Two units of alpha rate measurement are available.
0.000 cpm (counts per minute)
0.000 uCi/m x m (micro-Curie per square meter)
The alpha cps value indicated is true counts per second, not probe efficiency
adjusted.
uCi /m x m are for up to five alpha isotopes: Th-232, Ra-226, Am-241, U-238,
and Pu-239.
When µCi /m x m readings are required for other isotopes the indicated Alpha
µCi /m x m readings must be scaled according to the isotope.
