AI Article Synopsis
- The study measured the responses of two personal dosemeters (D-shuttle and Dose-i) on five different age-specific phantoms while simulating radiation exposure similar to the Fukushima nuclear accident using a 137Cs source.
- Results showed that while the dosemeter responses shifted based on their position on the phantoms, this shift was minor when contamination was evenly spread, and the responses decreased by about 10% as the body size of the phantoms increased.
- Although there were variations (~17%) in the ambient dose equivalent ratios between the two dosemeters, this was attributed to calibration differences; overall, both dosemeters effectively estimated age-dependent effective doses for radiation exposure.
Article Abstract
We experimentally obtained the responses of two personal dosemeters (PDs, D-shuttle and Dose-i) attached on five age-specific phantoms under rotational irradiation geometry, which simulated an environment that was radiologically affected by the 2011 Fukushima nuclear accident using of a 137Cs source. Although the PD responses showed an angular phase shift by the PD position on the phantoms, the angular dependence was small when the contamination was widely distributed. The PD responses decreased as much as ~10% with the increase in the phantoms' body size. Although there were ~17% variations in the PD/ADE (ambient dose equivalent) ratio depending on the different PDs, this variation was due to the fact that D-shuttle was calibrated with the inclusion of a safety margin. The PD/ADE ratios were similar to the effective dose to ADE ratios for corresponding age-specific phantoms. Our results suggest that these two PDs can provide reasonable estimates for age-dependent effective doses.

Eye lens dosimetry: does the direction of rotation (vertical or horizontal) play a role in type testing?

With the International Commission on Radiological Protection (ICRP) lowering the annual dose limit for the eye lens to 20 mSv, precise monitoring of eye lens exposure has become essential. The personal dose equivalent at a depth of 3 mm,(3), is the measurement method for monitoring the dose to the lens of the eye. Usual dosemeter type-test irradiations at non-normal angles of radiation incidence (≠ 0°) primarily use lateral radiation exposure scenarios, where radiation approaches from the left or right, necessitating rotation of the dosemeter-phantom setup around a vertical axis.

As the International Commission on Radiological Protection lowers the equivalent dose limit for lens of the eye of radiation workers, the importance of radiation protection for the lens of the eye has been increased. In the case of poor working condition, such as high temperatures and humid environments at nuclear power plants, wearing an eye dosemeter near the worker's eye may interfere with work. In addition, it would not be reasonable for all workers to wear an eye dosemeter to evaluate the lens equivalent dose even in areas with an expected low exposure dose in the NPPs.

Electromagnetic compatibility testing plays an important role in the type testing of radiation protection dosemeters in view of technical developments and the associated increase in electromagnetic fields. Lately, the use of inductive charging devices has grown as a user-friendly type of charging mobile-phones. In this article, we investigate their impact on active personal dosemeters (APD).

Aim: The aim of this study was to evaluate the occupational radiation exposure of staff during endoscopic retrograde cholangiopancreatography (ERCP), with a focus on individuals closest to the radiation source, and to identify potential increases in exposure to hands and eye lenses. Patient radiation exposure during ERCP was also assessed.
Materials And Methods: Staff organ doses were monitored using a Philips Allura Xper FD 20 fluoroscopy system, during 24 ERCP procedures for a period of 7 months.

The benefits of a cardiac resynchronization therapy (CRT) implantation are known in severe heart failure and its implantation may also be considered during pregnancy to ensure safe pregnancy and delivery for both the mother and the fetus. This study on a patient case aimed to estimate the absorbed dose (AD) to the fetus during the CRT implantation of 21st week of the pregnant woman. AD measurement was done using anthropomorphic phantom, radiophotoluminescence dosemeters and Monte Carlo simulation utilizing kerma area product (KAP) of the procedures.
