【摘要】：在六氟化鈾泄漏事故后果的評(píng)估中,除了關(guān)注鈾的放射性后果外,還需要關(guān)注泄漏物質(zhì)的化學(xué)毒性影響。在進(jìn)行化學(xué)毒性影響評(píng)估時(shí),如果采用半致死濃度作為評(píng)估標(biāo)準(zhǔn),則低估了六氟化鈾泄漏事故的影響半徑。在進(jìn)行六氟化鈾泄漏事故的環(huán)境影響評(píng)估時(shí),不僅要考慮泄漏物質(zhì)的致死效應(yīng),更應(yīng)該考慮泄漏物質(zhì)對事故地點(diǎn)周邊公眾的健康影響。美國環(huán)保署、美國工業(yè)衛(wèi)生協(xié)會(huì)等機(jī)構(gòu)均提出了相應(yīng)的化學(xué)濃度限值系列。對六氟化鈾事故后果評(píng)價(jià),推薦采用美國能源部推出的保護(hù)行動(dòng)限值(PACs)。
[Abstract]:In the assessment of the consequences of the uranium hexafluoride leak, besides the radioactive consequences of uranium, attention should be paid to the chemical toxicity of the leaking material. In the assessment of chemical toxicity, the radius of influence of uranium hexafluoride leakage accident is underestimated if the semi-lethal concentration is used as the assessment criterion. In the environmental impact assessment of uranium hexafluoride leakage accidents, not only the lethal effect of leaking substances should be considered, but also the health effects of leaking substances on the public around the accident site should be considered. EPA, the American Industrial Health Association and other organizations have proposed the corresponding chemical concentration limit series. For the assessment of the consequences of the uranium hexafluoride accident, it is recommended to adopt the protective action limit value (PACs).) issued by the United States Department of Energy.
