From the biological effects of radiation on human body , radiation effects are generally divided into two categories : " deterministic effects " and " stochastic effects " 確定性效應(yīng)及隨機(jī)性效應(yīng)輻射照射所做成的生物效應(yīng),通常分為確定性效應(yīng)和隨機(jī)性效應(yīng)兩大類。
The limitation on the effective dose provides sufficient protection for the skin against stochastic effects . an additional limit is needed for localized exposures in order to prevent deterministic effects 限值足以防止皮膚的隨機(jī)性效應(yīng),但對(duì)局部照射需設(shè)附加限值以防止確定性效應(yīng)。

Based on the model of linear quadratic relationship of dose - response , dosimetric method for assessment of deterministic hazard of low let radiation accident exposure in accordance with different time distribution of dose were developed in the paper by means of given thresholds of deterministic effects 輻射事故照射,除大劑量急性照射情況外,更多的還有受照延續(xù)時(shí)間不等、照射水平不一的多次受照情況,甚至尚有數(shù)天內(nèi)連續(xù)受照的。
