“…One of the biggest challenges associated with personal monitoring of staff in the health care sector is ensuring that staff reliably and regularly wear their dosemeters correctly and return the dosemeters for assessment at the end of the issue period. Recent professional body advice (Rogers et al 2017) described the robust management systems that need to be in place. These are covered in the working party report but are not discussed further here.…”

IPEM topical report: personal dose monitoring requirements in healthcare

et al. 2019

There are two major challenges for personal dosimetry in healthcare. The implications for interventional clinicians of the reduction in eye dose limit in the European Basic Safety Standards and UK regulations, and the large dose gradients across the hands of nuclear medicine staff who manipulate radionuclides. Guidelines on personal dosimetry have been prepared to address these and other issues. Collar dosemeters are recommended for assessment of eye doses for the majority of staff working with x-rays and, for interventional operators, dosemeters under their lead aprons to monitor effective dose together with eye dosemeters. When a dedicated eye dosemeter is worn together with lead glasses a correction might be required to allow for the protection provided. A dosemeter worn on the chest should provide an indication of eye dose for nuclear medicine workers. Finger doses for interventional clinicians can be monitored with ring dosemeters, but radionuclide workers may need to wear finger stalls if doses to fingertips are likely to be over 100 mSv. If only ring dosemeters are used, ratios for doses to the tip and base of the finger should be established. Guidance is given on levels where dose monitoring would be required and methods to predict dose levels based on local practices.

“…In report No.103 of the International Commission on Radiological Protection (ICRP), personal dose monitoring should consider deep individual dose, H p (10), and shallow individual dose, H p (0.07) [1]. The integrity of personal dose monitoring requires basic management, practical implementation, and dose record-keeping by a quali ed dosimetry service [2][3][4][5] The measurement accuracy of personal dosimeters is a critical issue.…”

This study was to determine the artificial factors considered for the measurement accuracy of personal dosimeter in dosimetry services under current performance test criteria. The investigation included management information questionnaire, on-site visit and blind test. The blind test with random selected personal badge was used in inter-comparison of eight dosimetry services, and the test results followed ANSI/HPS N13.11 criteria. This study also analyzed the measurement deviations if they felt in the criteria of ICRP 75 or not. One-way ANOVA tests were used to analyze the significant difference of the measurement deviations in different dosimetry services, irradiation categories, and years of use. Simple linear-regression test was performed for the significance of the prediction model between measurement deviations (category I, category II deep, and category II shallow) and readout frequencies. All visited dosimetry services followed the proper statue of basic management and passed the performance check of the tolerance level. There had significant differences of measurement deviation in different dosimetry services and irradiation categories but no significant difference in years of use. There was no significance in the linear-regression model between measurement deviation and badge readout frequencies. Based on the regular calibration of the personal dosimeter, the deviation of the measured value is mainly affected by different dosimetry services and irradiation categories; and there shows no significant influence by years of use and readout frequency.

This study was to determine the significance of factors considered for the measurement accuracy of personal dosimeter in dosimetry services such as dosimetry service, irradiation category, years of use and readout frequency. The investigation included management information questionnaire, on-site visit and blind test. The blind test with random selected personal badge was used in inter-comparison of eight dosimetry services, and the test results followed ANSI/HPS N13.11 criteria. This study also analyzed the measurement deviations if they felt in the criteria of ICRP 75 or not. One-way ANOVA tests were used to analyze the significant difference of the measurement deviations in different dosimetry services, irradiation categories, and years of use. Simple linear-regression test was performed for the significance of the prediction model between measurement deviations and readout frequencies. All visited dosimetry services followed the proper statue of basic management and passed the performance check of the tolerance level. The average deviations corresponding to category I, category II deep dose, and category II shallow dose were 6.08%, 9.49%, and 10.41% respectively. There had significant differences of measurement deviation in different dosimetry services (p < 0.0001) and irradiation categories (p = 0.016) but no significant difference in years of use (p = 0.498). There was no significance in the linear-regression model between measurement deviation and badge readout frequencies. Based on the regular calibration of the personal dosimeter, the deviation of the measured value is mainly affected by different dosimetry services and irradiation categories; and there shows no significant influence by years of use and readout frequency.
