Surface Contamination X-ray Radiation Meter Radiation Checking
Device X-ray Radiation Detector
End window counting tube area 18x10cm Surface contamination
measurement instrument FJ39-2180
Introduction
FJ39-2180 α,β Measuring 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.
