Surface Contamination (Bq; Dps; Dpm, Bq/Cm ); Dose Rate (Sv/H; R/H; Rem/H, Gy/H) - Thermo Scientific RadEye B20 Operating Instructions Manual

measurement of alpha contamination a surface contamination
detector with true alpha beta discrimination is required (e.g.
RadEye AB 100).
5.2 Surface Contamination (Bq; dps; dpm, Bq/cm
Up to 15 nuclides together with their related calibration factors
can be stored in the RadEye B20. The name of isotopes, the num-
ber of available nuclides as well as their 4 Pi efficiency can be
edited in the PC-software.
The user of the RadEye B20 can select the required isotope in the
menu <Nuclide>. This selected nuclide (e.g. Co-60) is displayed
in the LCD (eventually alternating to the subtracted background
activity in case of a net measurement).

Dose Rate (Sv/h; R/h; Rem/h, Gy/h)

The RadEye B20 can be used to measure dose equivalent
rates (Sv/h, Rem/h) – eventually by using appropriate gamma
energy filters.
If the energy filter is applied, the RadEye switches over to dose
rate display automatically.
The user may as well select R/h or Gy/h as a displayed measuring
unit with the understanding that 1 R/h is simply set equal to 1
Rem/h (1Gy/h = 0.8 7719 Rem/h) and that consequently energy
dependant deviations to the exposure rate and air kerma rate will
occur.
