本文主要讨论国际放射防护委员会(ICRP)新建议书(第60号出版物)中关于医学照射防护体系基本概念和原则的进化,以及在实施中需强调注意的一些问题。 2. InICRP1990 Recommendations,a new weighting factor——radiation weighting factorW_R was introduced to replace the quality factor Q for modifying the absorbed do...
Radiation weighting factorsequivalent dosequality factorcubical neutron dosimeterBD-100R detectorThe latest radiobiological findings show that the damage caused by the neutrons to human body is far greater than was previously thought. The International Commission on Radiological Protection, therefore, revised...
It is shown here that (i) a constant value of 10 is not consistent with weighting factors recommended by the ICRP for neutrons and (ii) it does not account for the hardening of the neutron spectra in Hiroshima and Nagasaki, which takes place with increasing distance from the hypo-centres....

factors and the radiation weighting factors. These results demonstrate the usefulness of dose conversion coefficients in space dosimetry. We would like to express our appreciation to the members of the ICRP task group on radiation exposures of astronauts in space for their valuable comments and ...
The tissue weighting factors recommended by ICRP to calculate effective doses are compared with relative damage factors calculated by ICRP for the nominal population and with similar factors calculated in this work for separate population cohorts in theRussian Federation. The significance of differences ...
The data that have been used in almost all calculations of MIRD S value absorbed dose and effective dose are based on stylized anatomic computational phantoms and tissue-weighting factors adopted by the International Commission on Radiological Protection (ICRP) in its publication 60. The more ...
