  1. 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，假若環境伽瑪劑量率持續高達每小時1000微希沃特超過本底值3000倍，則在5小時內，因為環境伽瑪輻射所引致的總劑量便可能達到上述的5000微希沃特。若環境伽瑪劑量率每小時200微希沃特超過本底值600倍，則個人須持續受此輻射影響25小時，所受的總劑量方可達到上述5000微希沃特。
