DESCRPTION
Uses :
Half life of radioactive substances.
Variation of rate with distance
Absorption of radiation
The Radioactive count rate Sensormeter measures radioactive count rates from 2 to 1000 counts per second in three ranges. The Sensormeter has a quiet click sounder giving an indication of count rate which may be switched off if not required. The combined Geiger tube and connecting lead supplied separately. enable the detection of alpha, beta and gamma radiation and is easily hand held or clamped at a set distance from the source. A protective cap is supplied with Geiger prob which will block alpha and most beta particles but allows gamma rays through .
Linearity ±0.5% 20 to 1000 counts S-1,assuming best rang is used
Time Constant 3.3s or 0.33s switchable.
Battery life 40 hrs constant use typical with MN 1604
