Through this selection, the sensitivity of the sensor is adapted per-
fectly to the isotope. The normal reduction of source activity through
radioactive decay is thus taken into account.
The MINITRAC 31 requires this information for the automatic decay
compensation. This ensures error-free measurement over the entire
lifetime of the gamma emitter - an annual recalibration is not neces-
sary.
