Comparison of radiation-shielding curtains for endoscopic retrograde cholangiopancreatography staff J. Radiol. Prot. (IF 1.4) Pub Date : 2024-09-24 Hiroki Ishii, Koichi Chida, Yohei Inaba, Shu Onodera, Masahiro Sai and Masayuki Zuguchi
Occupational radiation exposure to the eye lens of medical staff during endoscopic retrograde cholangiopancreatography (ERCP) should be kept low so as not to exceed annual dose limits. Dose should be low to avoid tissue reactions and minimizing stochastic effects. It is known that the head and neck of the staff are exposed to more scattered radiation in an over-couch tube system than in a C-arm system

Cavity ionization chamber responses in the JAEA and the NMIJ high-energy photon reference fields for radiation protection J. Radiol. Prot. (IF 1.4) Pub Date : 2024-09-19 Junya Ishii, Morihito Shimizu, Masahiro Kato, Tadahiro Kurosawa, Tomoya Tsuji, Hiroshi Yoshitomi, Yoshihiko Tanimura and Hiroshi Watabe
A dosimeter should ideally be calibrated in a reference field with similar energy and doserate to that which the dosimeter is being used to measure. Environments around nuclear reactors and radiation therapy facilities have high-energy photons with energies exceeding that of 60Co gamma rays, and controlling exposure to these photons is important.

Designing an improved model of the adult female ICRP reference phantom dedicated to mammography procedure J. Radiol. Prot. (IF 1.4) Pub Date : 2024-06-28 Atiyeh Ebrahimi-Khankook, Alireza Vejdani-Noghreiyan, Hamidreza Khodajou-Chokami, Zahra Abbasi-Khiabani
Mammography is an x-ray-based imaging method to examine breast abnormalities. Since low-energy photons are used in mammography, doses to different organs would depend strongly on the phantom posture and anatomy. Until now, a few studies have been performed on doses delivered to different organs during mammography. However, in none of them, the correct posture of the patient has been considered. In

Object and person tracking systems to enable extremity dosimetry in nuclear medicine using computational methods J. Radiol. Prot. (IF 1.4) Pub Date : 2024-06-25 Daniel Santiago Rondón, Pasquale Lombardo, Mahmoud Abdelrahman, Lara Struelens, Filip Vanhavere, Niki Bergans
Nuclear medicine (NM) professionals are potentially exposed to high doses of ionising radiation, particularly in the skin of the hands. Ring dosimeters are used by the workers to ensure extremity doses are kept below the legal limits. However, ring dosimeters are often susceptible to large uncertainties, so it is difficult to ensure a correct measurement using the traditional occupational monitoring

Age-based diagnostic reference levels and achievable doses for paediatric CT: a survey in Shanghai, China J. Radiol. Prot. (IF 1.4) Pub Date : 2024-04-23 Fanqiaochu Yang, Linfeng Gao
Computed tomography (CT) is extensively utilised in medical diagnostics due to its notable radiographic superiority. However, the cancer risk associated with CT examinations, particularly in children, is of significant concern. The assessment of cancer risk relies on the radiation dose to examinees. Diagnostic reference levels (DRLs) and achievable doses (ADs) were used to assess the level of radiation

Relevance of radon progeny measurements for the assessment of inhalation doses in groundwater utilities J. Radiol. Prot. (IF 1.4) Pub Date : 2024-04-17 Jukka T Tyrväinen, Jonne Naarala and Tuukka Turtiainen
The high radon concentrations measured in the indoor air of groundwater facilities and the prevalence of the problem have been known for several years. Unlike in other workplaces, in groundwater plants, radon is released into the air from the water treatment processes. During the measurements of this study, the average radon concentrations varied from 500 to 8800 Bq m–3. In addition, the indoor air

Radiation protection in a cohort of healthcare workers: knowledge, attitude, practices, feelings and IR-exposure in French hospitals J. Radiol. Prot. (IF 1.4) Pub Date : 2024-04-15 Clémence Baudin, Blandine Vacquier, Guillemette Thin, Lamine Chenene, Joël Guersen, Isabelle Partarrieu, Martine Louet, Hubert Ducou le Pointe, Stéphanie Mora, Catherine Verdun-Esquer, Philippe Lestavel, Frédéric Rousseau, Hervé Roy, Lynda Bensefa-Colas, Louis Boyer and Marie-Odile Bernier
The number of healthcare workers occupationally exposed to ionizing radiation (IR) is increasing every year. As health effects from exposure to low doses IR have been reported, radiation protection (RP) in the context of occupational activities is a major concern. This study aims to assess the compliance of healthcare workers with RP policies, according to their registered cumulative dose, profession

Occupational skin dose from radionuclide contamination: one country’s approach at standardising skin dose estimates using Varskin+ J. Radiol. Prot. (IF 1.4) Pub Date : 2024-04-09 Katherine Sharpe, Stephen McCallum, Janice O’Neill, Carolyn Paterson, Jennifer McCormick and Kate Sexton
The manipulation of unsealed radiopharmaceuticals by healthcare workers can cause accidental personal contamination leading to occupational radiation skin dose. The UK Ionising Radiations Regulations 2017 require that potential skin doses arising from reasonably foreseeable accident scenarios are included in risk assessments. Workers must be designated as classified if these dose estimates exceed 150
