Description
Overview
GAOTek radioactive surface contamination instrument is suitable for the low levels α, β Radiation surface contamination detection. The instrument adopt double flash detector, has the high detection efficiency; The same probe can measure at the same time α,β,γ, And automatically distinguish among α,β,γ, and particles and radiation dose rate, is the environment, nuclear medicine and molecular biology lab, radiation chemistry, nuclear materials transportation, storage, and the inspection of areas such as alpha, beta radiation surface contamination detection of the ideal instrument.
