| 摘 要： | 本文报道1984年7月至1985年6月间在本院实验室内测定的氡、(气土)浓度随季节和昼夜变化的情况。结果表明氡浓度的昼夜变化为早晨6—7时较高,下午1—3时较低,最高与最低值之比达3—4倍,接近日平均水平的时间为上午8—11时;氡、(气土)浓度随季节的变化规律相似,都是冬季(1—3月)较高,夏季(6—9月)较低,氡、(气土)月平均浓度的最高和最低值之比,分别为7.0和5.0倍,春(4—5月)、秋季(10—12月)的氡,(气土)浓度都分别与其年平均水平接近。

| Abstract: | The paper reported the concentration of ~(222)Rn and ~(220)Rn inour experimental room changed with the season and the day and night fromJuly 1984 to June 1985.The result showed that the change of ~(222)Rn withthe day and night,it is higher at 6 to 7 A.M..and the lower at 1 to 3P.M..The ratio of the highest to the lowest is 3 to 4.The time at whichthe concentration approximates to the average concentration of the day is at8 to 11 0'clock in the morning.The charge rule of ~(222)Rn and ~(220)Rn con-centration with the season was similar,it is all higher in the winter(fromJanuary to march)but the lower in the summer(from June to September),for month's average concentration of ~(222)Rn and ~(220)Rn the ratio of the highestto the lowest is 7.0 and 5.0,respectively.The concentration in the spring(from April to May)and in the autumn(from October to December)allapproximated to the annual average value respectively. |
