AT1117M Radiation Monitor (Alpha/Beta Contamination Monitor)

The following configuration of the radiation monitor can be used for:
– Alpha particles flux density and surface activity measurements of 239Pu with BDPA-02 / BDPA-03
– Beta particles flux density and surface activity measurements of 90Sr+90Y with BDPB-02 / BDPB-03

 

  • High sensitivity
  • Sound, light, and visual alarm for exceeded threshold levels
  • Can be operated both as a stationary and portable instrument
  • Wide measurement range
