Abstract:
Objective To compare,through experimental measurements,the differences between four kinds of single and double dosimetry algorithms recommend by ICRP 139 Publication in estimating interventional radiology staff's effective dose,with aim to realize the applicability of algorithms for cardiovascular interventional diagnosis and treatment in China.Methods Measurements of organ doses were carried out with an anthropomorphic phantom equipped with thermoluminecent dosimetry and dressed with lead apron and lead collar.The effective doses were calculated using the tissue weighting factors.Meanwhile,the staff's effective doses were also obtained by the use of four kinds of single and double dosimetry algorithms.The later four effective doses were compared with those obtained with phantom methode.Results The effective doses were 0.581 mSv for phantom method,0.667 mSv for Swiss ordinance's algorithm,0.484 mSv for McEwan's algorithm,0.485 mSv for von Boetticher's algorithm and 0.726 mSv for Martin-Magee's algorithm,in ICRP 139 report respectively.The relative deviations to the results of experimental measurement were 14.8％ for Swiss ordinance's algorithm,-16.7％ for McEwan's algorithm,-16.5％ for von Boetticher's algorithm and 24.9％ for Martin-Magee's algorithm,respectively.Conclusions There are great differences between the effective doses of the first operator obtained by four dosimetry algorithms and the simulated result.From the point of view of radiation protection,it is recommended to use the Swiss ordinance's algorithm to carry out individual monitoring of the first operator in the cardiovascular interventional procedures.
