Estimates of cancer risks from exposure to ionising radiation are essential in occupational radiation protection, helping to form the basis for dose limits and guiding the optimisation process. Risk estimates may also be required for leg... R Harbron - 《Journal of Radiological Protection》 被引量...
All these values are within the ICRP recommended dose limits. Extrapolated to 725 examinations per year, the resulting effective dose measured with TLD would be 10 mSv with unshielded and 7.5 mSv with shielded syringes, respectively (25 % dose reduction). The doses measured by TLD were ...
the available evidence for certain types of tumour points to the need for an accuracy of 卤5% in the delivery of an absorbed dose to a target volume if the eradication of the primary tumour is sought". The ICRU continues, "Some clinicians have requested even closer limits such as 卤2%, ...
DOSE COEFFICIENTThe present IAEA Transport Regulation on surface contamination (with limits specified in terms of Bq cm-2) is determined from a simple radiological model for the most hazardous radionuclides (Pu-239 for α emitters and Sr-90 for β emitters) and its extremely conservative model i...
Moreover, the dose calculation accuracy of VMAT plans using jaw tracking may be affected because the jaws adjust their size to the MLC apertures to minimize the radiation leakage. Thus, if static and modulated dose delivery to very small targets is planned, then it is required to measure a ...
