Response test with test adapter
The test-adapter 42506/8371 offers a convenient way to verify the
radiation response performance of the RadEye AB100. This
"check source" contains 80 g of natural Lu2O3 (which corre-
sponds to approximately 4000 Bq Lu-176). Due to self-absorption
in the Lu2O3 ceramics bulk material, the beta surface emission
rate is only approximately 80 1/s, which results in a net count rate
of the RadEye AB100 of 45 cps. The operational advantage of the
test-adapter is given by the fact that each and every individual
adapter has the same emission rate, and that due to the long life
time (3.6E10 years), which exceeds the age of the universe signif-
icantly, neither source specimen, nor half life corrections need to
be performed. Furthermore the specific radioactivity (approxi-
mately 48 Bq/g) of natural Lu2O3 is well below the threshold
