| 7. | Fallout of radioactive substances resulting from atmospheric nuclear weapon testing , luminous watches , ionization chambers , smoke detectors , etc . make up the balance
其馀的来源有大气层核试产生的放射性尘埃、夜光表、电离室、烟雾探测器等。 |
| 8. | A number of atmospheric nuclear tests took place from 1945 to 1980 . radioactive particulates produced in the explosions dispersed into the atmosphere by the winds and some of them deposited onto the ground
在一九四五年至一九八零年期间，世界各地进行了多次大气核试爆，所产生的放射性尘埃随风扩散，部份沉降到地上。 |
| 9. | Following a relevant united nations general assembly resolution , the hong kong observatory started measuring radioactivity in 1961 to monitor radioactivity in air which might affect the health of the local population and to determine , as part of an international network , the global atmospheric transport of radioactive dust and other contaminated substances
根据联合国大会通过的相关决议，香港天文台于1961年开始监测大气中可能影响市民健康的放射性物质，并作为国际测量网的一部份，测定大气中放射性尘埃及其他污染物的全球迁移情况。 |
| 10. | A number of atmospheric nuclear tests took place from 1945 to 1980 . radioactive particulates produced in the explosions dispersed into the atmosphere by the winds and some of them deposited onto the ground . deposition of these radioactive materials increased the level of artificial radiation in the environment
在一九四五年至一九八零年期间，世界各地进行了多次大气核试爆，所产生的放射性尘埃随风扩散，部份沉降到地上。这些放射性沉积物为我们自然环境增加了额外的人工辐射。 |
