Effect of the radiation protective apron on the response of active and passive personal dosemeters used in interventional radiology and cardiology
In fluoroscopy guided interventional procedures, workers use protective garments and often two
personal dosemeters, the readings of which are used for the estimation of the effective dose;
whereas the dosemeter above the protection can be used for the estimation of the equivalent dose of
the lens of the eye. When a protective apron is worn the scattered field that reaches the dosemeter
is different from the case where no protection is used; this study analyses the changes in the
response of seven passive and eight active personal dosemeters (APDs) when they are placed above a
lead or lead equivalent garment for S-Cs and x-ray diagnostic qualities. Monte Carlo simulations are
used to support the experimental results. It is found that for passive dosemeters, the influence on
the dosemeter ’s response to the lead or lead equivalent was within the range 15%–38% for the x-ray
qualities. This effect is smaller, of the order of 10%, when lead-free garments are used, and much
smaller, wi...
