本文介绍用负高压静电收集和测量人体呼出气中氢子体置装,测定了白云鄂博矿按比例分层随机抽样的130名接触粉尘工人呼出气中的氢活度,并据此推算出肺内天然钍的沉积量。对其卫生意义也作出了评论。
This article describes the use of negative high-voltage electrostatic collection and measurement of the body’s exhaled hydrogen in the body of hydrogen-loaded, measured Bayan Obo mine stratified random sampling of 130 exposed dust workers in the exhaled breath hydrogen activity and thus calculate the lung The amount of natural thorium deposition. Also made comments on its health significance.
