【摘要】 我们通过呼出氡的测定方法调查了92名接触含镭夜光粉工人和45名未接触夜光粉工人的体内镭含量。结果表明,不接触夜光粉工人的平均体内镭含量为2.7×10^-4微居里,接触民用夜光粉者为5.9 ×16^-4微居里;而接触军用夜光粉者为9.9×10^-4微居里,其中体内含镭量最高者达57.2×10^-4微居里。更多还原

【Abstract】 Using the determination method for radon in breath,wehave investigated the radium body contents of 92 luminescent powder paint-ers and 45 other workers who are not in contact with luminescent powderIt is found that the average radium body contact of the workers not conta-cting with luminescent powder is 2.7×10^-4Ci,that of the civil industrypainters,5.9×1O^-4μCi,that of the military industry painters 9.9×10^-4μCi,and the maximum body content among them is 57.2×10^-4μCi.更多还原
