摘要:

运用本实验室建立的大气沉降中⁷Be,²¹⁰Pb的γ谱分析方法和²¹⁰Po的α谱分析方法,测定了青岛大气沉降通量。结果表明,青岛市2002年4～11月大气沉降的⁷Be和²¹⁰Pb通量平均为1.67和0.32 Bq/(m²·d);2004年5～9月⁷Be,²¹⁰Pb和²¹⁰Po通量平均值为2.15,0.51和0.083 Bq/(m²·d)。

Measurements of atmospheric deposition fluxes of ⁷Be, ²¹⁰Pb and ²¹⁰Po

Abstract:

The measurement methods of atmospheric deposition fluxes of ⁷Be, ²¹⁰Pb and ²¹⁰Po have been developed, ⁷Be and ²¹⁰Pb are measured by γ spectroscopy, and ²¹⁰Po is determined using α spectroscopy. The formulas from the activities of measuring time to deposition spectroscopy have been deduced. The formulas from the activities of measuring time to deposition fluxes have been deduced, too. The atmospheric deposition fluxes of ⁷Be, ²¹⁰Pb and ²¹⁰Po at Qingdao have been studies. The result shows that the average fluxes of ⁷Be, ²¹⁰Pb are 1.67 and 0.32 Bq/(m²·d) respectively during April to November 2002 and average fluxes of ⁷Be, ²¹⁰Pb and ²¹⁰Po are 2.15, 0.51 and 0.083 Bq/(m²·d) during May to September 2004.
