摘要
介绍了一种便携式就地 Na I( Tl) γ谱仪 ,该系统可用于环境或核事故后就地 γ能谱的测量 ,给出了环境中放射性核素的组成及各自的质量活度 ( Bq/kg)或表面活度 ( Bq/cm2 )和地面 1m高度的周围吸收剂量率 ( Gy/h)
The paper describes a portable in situ NaI( Tl) γ spectroscopy system, which consists of a NaI(Tl) scintillation detector, an integrative spectroscopy card, a notebook computer and spectroscopy software. The spectrometer addresses applications in environmental or nuclear accident in situ γ spectroscopy measurements, and gives valid quantitative results of radionuclide concentrations per unit volume (Bq/kg) or unit area (Bq/cm 2) in the soil and absorbed dose rate in air at 1 m above ground (Gy/h).
