The international commission on radiological protection ( icrp ) considers that if the annual radiation doses to the lens of the eyes of radiation workers are restricted to 150 msv ( equivalent to 150 mgy for x - ray ) , cataract is unlikely to occur during hisher life assuming a working period of 50 years 國際輻射防護委員會( icrp )認為,輻射工作者的眼晶體所受劑量只要限制在每年150毫希以下(對于x射線,等于150毫戈以下) ,因輻射誘發的白內障在他她一生中(假設工作五十年)都不會出現。

To ensure that no individual is exposed to radiation risks that are judged to be unacceptable . in the unlikely event of a nuclear accident resulting in an increase of environmental radiation level , both icrp publication no . 60 and no . 63 recommended implementation of interventions i . e . human activities to reduce the overall exposure by altering the existing causes of exposure . the basic principles for intervention are 對于因核意外而令自然環境輻射水平增加,國際放射防護委員會在其一九九零年的建議書第60號刊物及一九九一年的建議書第63號刊物內,均建議需進行干預即通過某些活動影響已存在的照射原因,從而降低總照射量,保障受到影響的人的健康,其防護原則為:

However , such a model only takes into account some certain factors , and do not touch uncertain factors such as social factor and public psychology etc . , which are but of importance in the nuclear emergency decision - making system . any decision on counter - measures to protect the public should be made based upon the basic pr 而這些因素在核應急決策中相當重要,任何保護公眾的對策都必須建立在icrp推薦的基本原則上,這些原則的應用需要在費用與輻射方面的比較,考慮很多主觀因素和不確定因素。

The international commission for radiological protection icrp estimates that an additional death rate of 12 . 5 persons per million for every msv of exposure . this means that if a million people were given 2 msv of radiation , the expected additional death rate from cancer would be 25 additional persons or 230 , 025 instead of 230 , 000 persons out of a million dying from naturally occurring cancer 據國際放射防護委員會估計,每一百萬人每接觸到一毫西韋特輻照量所引致的死亡率增幅為12 . 5 % ,換言之,如一百萬人接觸到兩毫西韋特的輻射,因死亡的人數估計會增加二十五人,亦即每一百萬人會有二十三萬零二十五人自然死于癌癥。

The fact that there is no level of radiation which can be proven to cause no harm means that the international commission for radiological protection icrp recommends that no practice involving radiation be undertaken unless it is likely to bring a net benefit and that for any such practice , exposure should be kept as low as reasonably achievable alara principle , economic and social considerations being taken into account 由于任何輻射量都不能確保絕對安全,國際放射防護委員會在考慮經濟及社會因素后,建議盡量避免涉及輻射的治療或行為,除非所得的益處較輻射引致的壞影響大,并且在進行的過程中,應把輻照量維持在可合理使用最低劑量alara原則。

Any practice resulting in increased exposure to radiation should be carefully planned in accordance with the three basic radiological protective principles as set out by the international commission on radiological protection icrp in 1991 icrp publication no . 60 . these basic principles are 對于因進行任何活動,而增加了個人或群體的輻射照射,國際放射防護委員會icrp在其一九九零年的建議書第60號刊物內,列出三項基本輻射防護原則:

International standard in the 1990 recommendations of the international commission on radiological protection icrp publication no . 60 , the recommended dose limits for exposure associated with practice are as follows 國際放射防護委員會在其一九九零年的建議書第60號刊物內,對于因活動而引致的輻射照射,建議的劑量限值如下:

The following intervention levels are recommended by the international commission on radiological protection icrp publication no . 63 國際放射防護委員會在其一九九一年的建議書第63號刊物內,建議以下的干預水平:
