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 ...
A new "quality-control-based (QC-based) dose survey method" has been developed for determination of diagnostic reference levels (DRL) in Computed Tomograph... M Parsi,M Sohrabi,F Mianji,... - 《Health Physics》 被引量: 2发表: 2018年 Defining the Limits of Scrutiny of Awards Based on ...
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%, ...
Further research is required about accuracy limits in calculations and measurements for very small field sizes. 4. Conclusions The accuracy of Acuros® XB for small field dosimetry calculation was evaluated by using the formalism proposed by the code of practice IAEA/AAPM TRS-483. Acuros® XB ...
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 ...
