是由十个固定的辐射监测站组成，二十四小时不停量度香港的环境伽马剂量率。 |
| 4. | A network has also been established for continuous monitoring of the ambient gamma dose rate in hong kong and to warn of any deviation from normal levels
天文台并设立了一个辐射监测网络，不断监测境内空气中的伽玛剂量比率，当剂量比率超出正常辐射水平时，监测网络便会发出警告。 |
| 5. | As it is necessary to obtain timely information , early phase monitoring focuses on the measurement of ambient gamma dose rates , concentrations of gamma - emitting radionuclides and gross alpha beta levels
因为需要及时提供有关辐射水平的资料，早期辐射监测会集中量度环境伽马剂量率伽马放射性核素活度浓度及总阿尔法及贝他活度浓度。 |
| 6. | As it is necessary to obtain timely information , early phase monitoring focuses on the measurement of ambient gamma dose rates , concentrations of gamma - emitting radionuclides and gross alphabeta levels
因为需要及时提供有关辐射水平的资料，早期辐射监测会集中量度环境伽马剂量率、伽马放射性核素活度浓度及总阿尔法及贝他活度浓度。 |
| 7. | The objective of emergency radiological surveys is to enhance the spatial coverage of the monitoring of the ambient gamma dose rates , especially over sea areas between the nuclear power stations and hong kong as well as over remote areas of the territory
进行应急辐射巡测应急辐射巡测的目的是为加强监测环境伽马剂量率的分布，特别针对位于核电站与香港之间的海域及偏远地区。 |
| 8. | The survey team conducts surveys along pre - designated survey routes in the northeast part of the new territories . it measures ambient gamma dose rates , surface activity concentrations of beta emitters at ground surface and in - situ gamma spectrum of land soil
流动巡测队会沿新界东北部预先选定的测量路线，在不同位置量度环境伽马辐射剂量率、地面的贝他放射体的表面活度浓度和原位置土壤的伽马能谱，以及收集大气飘尘、放射性碘、擦拭及其他环境样本。 |
| 9. | The average dose rates measured at the radiation monitoring stations over various parts of the territory were as follows : station yesterday s average microsieverts hour ping chau 0 . 09 tap mun 0 . 08 kat o 0 . 10 yuen ng fan 0 . 12 tai mei tuk 0 . 12 sha tau kok 0 . 10 kwun tong 0 . 13 sai wan ho 0 . 10 king s park 0 . 14 tsim bei tsui 0 . 13 note 1 from readings taken at various locations in hong kong during the period 1987 - 2005 , the background ambient gamma radiation levels may vary between 0 . 06 and 0 . 3 microsievert per hour . 2 protective action may be required if there is an increase in the ambient gamma dose rate above background such that the total additional dose is expected to exceed 5000 microsieverts
在香港各地区的辐射监测站所录得的平均数据详列如下：昨日平均环境伽玛辐射辐射监测站剂量率微希沃特小时平洲0 . 09塔门0 . 08吉澳0 . 10元五坟0 . 12大尾笃0 . 12沙头角0 . 10观塘0 . 13西湾河0 . 10京士柏0 . 14尖鼻咀0 . 13注释1 .根据1987年至2005年间在香港各地区所录得的数据显示，本港的本底环境伽玛辐射水平可以在每小时0 . 06至0 . 3微希沃特这范围内波动。 |
| 10. | 3 for example , if ambient gamma radiation is the only factor contributing to the radiation dose to a person , this dose of 5000 microsieverts may be reached when the ambient gamma dose rate is 1000 microsieverts per hour more than 3000 times above background and lasts for 5 hours ; or when the dose rate is 200 microsieverts per hour more than 600 times above background and lasts for 25 hours
3 .例如，假若环境伽玛剂量率持续高达每小时1000微希沃特超过本底值3000倍，则在5小时内，因为环境伽玛辐射所引致的总剂量便可能达到上述的5000微希沃特。若环境伽玛剂量率每小时200微希沃特超过本底值600倍，则个人须持续受此辐射影响25小时，所受的总剂量方可达到上述5000微希沃特。 |
