ICRP Publication 88 recommends doses to the embryo and fetus from intakes of radionuclides by the mother for various intake scenarios. Mainly by answering the question 'Is radiation protection for the unborn child guaranteed by radiation protection for female workers?' it has been assessed if the intake scenarios given in ICRP Publication 88 are adequate for radiation protection purposes. This is generally the case, but the consideration of an additional chronic intake scenario for early pregnancy would be helpful. It is demonstrated that following chronic intake by inhalation, for most radionuclides radiation protection for (female) workers is also adequate for protection of the unborn child, considered as a member of the public. However, there are a number of radionuclides for which possible intakes in routine operations should be more restricted (up to 1% of the annual limits on intake for workers in the case of nickel isotopes) to ensure radiation protection for the unborn child.
国际放射防护委员会第88号出版物针对母亲摄入放射性核素的各种情况,推荐了对胚胎和胎儿的剂量。主要通过回答“女工的辐射防护能否确保未出生胎儿的辐射防护?”这一问题,评估了国际放射防护委员会第88号出版物中给出的摄入情况是否适用于辐射防护目的。通常情况下确实如此,但考虑增加一种针对早孕的慢性摄入情况会有所帮助。结果表明,吸入后长期摄入时,对于大多数放射性核素,(女工的)辐射防护对于作为公众成员的未出生胎儿的防护也是足够的。然而,有一些放射性核素,在常规操作中可能的摄入量应受到更严格限制(对于镍同位素,可达工人年摄入量限值的1%),以确保对未出生胎儿的辐射防护。
