EURADOS intercomparison IC2020ph on whole body dosemeters for photons.
Radiat Prot Dosimetry
October 2023
The European Dosimetry Group has been organising international intercomparisons (ICs) for personal dosemeters on a regular basis. The IC announced in 2020 was postponed to the end of 2020 and the beginning of 2021 due to coronavirus (COVID-19) restrictions. The irradiation plan consisted of nine irradiation setups with five different photon radiation qualities (S-Cs, S-Co, N-150, W-60, W-80) and two different angles of irradiation incidence (0o and 60o).

- Estimating radiation exposure for workers in interventional procedures is tough, especially because these procedures can expose them to high doses of radiation.
- To protect themselves, workers are required to wear protective garments, prompting the need for accurate measurement techniques for doses received, particularly to the lens of the eye.
- The study examines data from four European dosimetry services to create practical guidelines for using personal dosimeters in such settings, also discussing the pros and cons of using one versus two dosimeters.
The safe use of radiation sources presupposes the engagement of personnel adequately educated and trained on radiation protection and with the necessary safety culture. This is necessary in order to understand their responsibilities and perform their duties in the safest way for themselves, the public and the patients, where appropriate. The Greek Atomic Energy Commission (EEAE) provides education and training on radiation protection to scientists, technical personnel and members of emergency response teams as well as the recognition of the related programs.

Different types of passive dosemeters were type-tested according to the International Electrotechnical Commission 62387 requirements. The uncertainty in measurement was calculated using the Guide to the Expression of Uncertainty in Measurement approach.

- This paper analyzes over 50 years of work practices in interventional cardiology, specifically focusing on radiation protection based on a study involving over 400 cardiologists across Europe conducted between 2014 and 2016.
- The study highlights the importance of using protective measures like ceiling-suspended lead shields and lead glasses to keep radiation exposure below safe limits, especially in haemodynamic procedures.
- While significant improvements in radiation protection tools have been observed, the paper notes that 7% of haemodynamic procedures still occur without any protective measures.
The lens of the eye is one of the radiosensitive tissues of the human body; if exposed to ionizing radiation can develop radiation-induced cataract at early ages. This study was held in Greece and included 44 Interventional Cardiologists (ICs) and an unexposed to radiation control group of 22 persons. Of the note, 26 ICs and the unexposed individuals underwent special eye examinations.
