多用途手持式核素检测仪以基于ARM7的多道分析器为核心
可选配电致冷CdTe半导体探测器或闪烁计数器。内嵌常见的天然和人工放射线核素库
可实现现场原位测量和核素检测。实验表明
CdTe探测器对59.54和0.662 keVγ射线的能量分辨率分别可达0.8和5.9 keV
能完成中、低能核素的检测。闪烁计数器可实现中、高能射线的核素检测。
A multi-purpose handheld radionuclide detection instrument has been developed
with an ARM7-based multi-channel analyzer
and optional detectors of CdTe or NaI(Tl) scintillator.Having a data base of common natural and artificial radioactive nuclides
it can realize in-situ field measurements and radionuclide detection.Testing results show that energy resolutions of CdTe detectors achieves 800 eV@59.54 keV(241Am) and 5.9 keV@0.662 keV(137Cs)
which are good enough for detecting nuclides of medium-low-energy γ-rays
while the NaI(Tl) detector can be used to detect nuclides of high-energy γ-rays.
