FHZ 691-10 Dose Rate Detector

Catalog number: 4254271
Detect even the smallest amounts of artificial radioactivity with a high sensitivity scintillation detector. The Thermo Scientific™ FHZ 691-10 probe is specially suited to detect dose rate increases as small as 3 percent at normal background within a measuring time of one minute. Using the Natural Background Rejection (NBR) algorithm, this low dose rate detector easily differentiates between artificial parts of radiation and fluctuations in the natural dose rate (e.g. caused by precipitation) in the surrounding environment.
