CAIRS-ALGADE personal alpha dosimeter

The CAIRS-ALGADE Personal Alpha Dosimeter (PAD) is a portable, lightweight personal monitoring system designed to measure individual exposures to radon and thoron progeny and Long-Lived Radioactive Dust (LLRD). The CAIRS-ALGADE Personal Alpha Dosimeter consists of a CAIRS track etch detectors (dosimeter head) mounted in an ALGADE individual air sampling system designed to be worn on the belt of the individual to be monitored. The PAD is worn by the individual for a period of one month. At the end of the month, the CAIRS dosimeter head is removed from the PAD and resumed to the CAIRS National Laboratories in Saskatoon, Saskatchewan to be processed. Exposure results are supplied to the respective clients on a monthly basis. We will briefly discuss the CAIRS-ALGADE Personal Alpha Dosimeter, its operation and its capabilities for measuring radon and thoron progeny and LLRD. (author)
