For Alpha, Beta, Gamma Particulates
Monitors Noble Gas and Iodine
The CAM-33 Series consists of two to six channel air monitors for simultaneous, continuous measurement of Gamma Particulates, Gross Beta with Gamma Particulates, Noble gaseous radioactivity, and Iodine. Batch sampling or dual sampling for continuous sampling during the course of an accident are options available with the Cam Series.
- The CAM-33-4 includes Alpha Particulate monitoring.
- The CAM-33-6 features six channels for measuring Alpha Particulates, Tritium, and Carbon-14.
- The CAM-3XG features three channels and measures Noble Gas energies: low, medium, and high with readout in Curie, MeV or µCi/cc.
- Electronics include a Computer with 17" Color LCD Monitor.
- Shields are void free lead encased in welded steel and with stainless steel liners for long, useful life and easy decontamination.
- Filters are easily changed via quick disconnect, o-ring sealed filter holder. Shield can be opened for filter change or cleaning with minimum effort. All shield connections and openings are sealed against air leaks.
