AT1329 Alpha and beta counter

Application

Specification

Alpha and beta counter is intended for simultaneous or separate measurement of a gross alpha and beta gross activity in various samples.

Sample counter can be used to:
- Measure gross alpha and gross beta activity of counting samples based on special aerosol filters
- Measure gross alpha and gross beta activity in "thick-layer" counting samples prepared from material (e.g. by evaporation, or any other method of preparing "thick-layer" sample)
- Measure gross alpha and gross beta activity in "thin-layer" counting samples prepared from material (e.g. by electrolytic deposition)
- Measure activity, flux density, external alpha and beta radiation for "thin" sources
- Control radiation contamination of surfaces by a smear method
