【摘要】 本文报道了我国１例室内空气中２１０Ｐｂ的浓度测定结果。１９９２年１－９月采集了一礼堂内空气样品，测得２１０Ｐｂ浓度为３．７４－６．２４ｍＢｑ·ｍ－３，平均值为４．６６ｍＢｑ·ｍ－３。作为对照，１９９２年２－１１月采集了阳台上的室外空气，测得２１０Ｐｂ浓度为１．２２－２．６６ｍＢｑ·ｍ－３，平均值为１．８４ｍＢｑ·ｍ－３。室内、外空气中的２１０Ｐｂ浓度之比约为２．５∶１。更多还原

【Abstract】 A measured value of 210 Pb Concentration in indoor air was reported. From Jan. to Sep. of 1992, air samples were collected in an auditorium, from which the 210 Pb indoor air concentration was measured of average value of 4.66 mBq·m -3 (3.74-6.24 mBq·m -3 ). For the sake of contrast, the air samples from the balcony of the auditorium were also collected from Feb. to Nov., from which the outdoor 210 Pb air concentration of average 1.84 mBq·m -3 (1.22-2.66 mBq·m -3 ) obtained.
