智能化核素活度计

An intelligential nuclide activity meter

本文介绍的智能化核素活度计由充氩井型电离室、MOS场效应管静电计测量头和Z80微型计算机组成。可测量^(226)Ra、^(60)Co、^(137)Cs、^(32)P、^(99m)Tc、^(113m)In、^(125)I、^(131)I等几十种常用核素的活度,是放射性同位素生产和应用中的计量仪器。活度值用4位数字显示。能存贮91个测样数据,并可将数据自动打印输出。 ^(226)Ra的测量范围为3.7Bq-3.7GBq。仪器有核衰变修正、扣除本底和自动检测故障的功能。

The instrument consists of an argon-filled well type ionization chamber, a MOSFET electrometer and a Z80 microcomputer. It can measure the activity of tens of common nuclides such as 226Ra, 60Co, 137Cs, 32P, 99mTc, 113mIn, 125I and 131I. It can be used as a calibrated instrument when the production and applications of radioisotopes are involved. The result of measurement are displayed in 4-digits. The instrument can storage 91 assayed data and print out the data automatically.The operating range is 3.7 Bq to 3.7 GBq for 226Ra. The functions of this instrument include correction for nuclear decay, background subtraction and automatical detection of trouble.
