The iSolo® system is a portable, firmware based, single-sample, manual, gas-less alpha /beta counter. The iSolo counter is designed for the analysis of air filters and most other types of alpha /beta samples. When analyzing air filters, the iSolo counter discriminates both radon and thoron and their progeny from transuranic and fission product materials on the air filter samples. The iSolo system weighs as little than 6.5 kg in its lightest configuration. The iSolo counter uses a solid state silicon PIPS detector for alpha and beta detection. The iSolo system can be operated for 10 hours or more with internal batteries and is totally self contained.
