AT1117M Radiation Monitor (Alpha/beta contamination monitor)

AT1117M Radiation Monitor (Alpha/beta contamination monitor)

This configuration of radiation monitor can be used for the following purposes:
- Measure alpha particles flux density and surface activity of 239Pu with BDPA-02 / BDPA-03
- Measure beta particles flux density and surface activity of 90Sr+90Y with BDPB-02 / BDPB-03
 
  • High sensitivity
  • Sound, light and visual alarm for exceeded threshold levels
  • Can be operated both as fixed and portable instrument
  • Wide measurement range
