介招了应用十进管的轻型计数装置。定标系数10~6,强度计由0至2·10~6脉冲/分有10档计数率测程。计数器的供电高压源具有四个扩展档,调节电压由0至1600伏。装置的特点是使用极方便。治耗功率为40瓦,外廓尺寸375×235×160毫米~3,重量7公斤。为了测量α、β和γ辐射源的放射性强度,目前是应用-1、-2和-10000型装置;它们具有严重的缺点,如体积大,量重大,计数率低,计数器电源电压建立的惯性大,等等。作者设计出一种轻型计数装置试样(如图),它避免了上述缺点且具有通用的使用机能。
Introduced the use of ten-pipe light counting device. Calibration coefficient of 10 to 6, the intensity meter from 0 to 2 · 10 ~ 6 pulses / min 10 gear count rate range. Counter power supply High-pressure source has four extensions, the adjustment voltage from 0 to 1600 volts. The device is characterized by extremely easy to use. Governance power consumption of 40 watts, dimensions 375 × 235 × 160 mm ~ 3, weight 7 kg. In order to measure the radioactive intensity of α, β and γ radiation sources, devices of the -1, -2 and -10000 types are currently used; they have serious disadvantages such as large volume, large volume, low count rate, inertia established by the counter supply voltage Big, and so on. The authors devised a sample of a light-duty counting device (pictured) that avoids the above drawbacks and has universal usability.
