长期吸入氡将在人体脂肪和体液中形成氡的贮存库。倘若一个人由氡浓度较高的环境转移到氡浓度较低的环境,将呼出贮存在体内的氡。氡的初始呼出率取决于吸入的氡浓度。本文描述了体内氡及其子体的行为,以及氡呼出率与进食后时间的关系。已经观察到饭后氡呼出率有较大的、但持续时间不长的增加。进食对体内没有镭的人的氡呼出率的影响与对体内有镭的人的氡呼出率的影响是类似的。应该指出胸腔内的大量的氡子体的放射性可能影响对体内钚或其他锕系元素的测量。
Long-term inhalation of radon will form a reservoir of radon in body fat and body fluids. If a person is transferred from a higher radon concentration environment to a lower radon concentration environment, radon stored in the body will be exhaled. The initial outtake of radon depends on the concentration of radon inhaled. This article describes the behavior of radon and its daughters in vivo, and the relationship between exhaled breath rate and time after eating. Postprandial radon exhalation rates have been observed to be larger, but not longer duration increases. The effect of feeding on radon exhalation rates for people who do not have radium in vivo is similar to the effect on radon exhalation rate for people who have radium in the body. It should be noted that the radioactivity of a large number of radon progeny in the thorax may affect the measurement of plutonium or other actinides in the body.
