Evaluation of Environmental Radiation Exposure and Algorithms for Determining the Occupational Effective Dose During 99mTc-MDP Bone Scintigraphy: A Comprehensive Analysis

Applied Sciences, Journal Year: 2024, Volume and Issue: 14(23), P. 11211 - 11211

Published: Dec. 2, 2024

This study evaluated the occupational exposure of radiopharmacists, nurses, radiological technologists, and technologist assistants involved in 99mTc-MDP bone scintigraphy procedures. Actual effective doses for individual staff needed ascertaining. An environmental radiation audit revealed all nuclear medicine areas were compliant with ICRP IAEA guidelines. To ascertain doses, they recorded by OSL badges. The highest was to Hp(0.07) 2.19 µSv during radiolabeling. nurse administering a dose 0.27 at Hp(0.07), 26.01% total dose. assistant receive 73.05% However, received positioning patients SPECT/CT scans, an 32.03 µSv. Single double dosimetry estimate algorithms evaluated, resulting being more accurate. Padovani et al. algorithm found most closely align actual values (p > 0.05), thereby validating measurement methods used this study. research offers benchmark applicable audits continuous effort enhance safety personnel scintigraphy.

Cancer and Non-Cancer Effects Following Ionizing Irradiation

Cancers, Journal Year: 2024, Volume and Issue: 16(6), P. 1141 - 1141

Published: March 13, 2024

On the one hand, ionizing radiation has been used to treat not only cancer, but also non-cancer diseases. other associations with exposure have increasingly reported for diseases, both at doses or dose rates much lower than previously suggested considered. This underscores need considering cancer and effects of medical (diagnostic therapeutic), occupational environmental radiation. As such, this Special Issue aims serve as a forum gather latest developments discuss future prospects in field normal tissue responses exposure. The is composed 18 articles outlining arising various tissues (e.g., those circulatory, sensory, nervous, respiratory, reproductive systems).

Radiation Adverse Outcome pathways (AOPs): examining priority questions from an international horizon-style exercise

International Journal of Radiation Biology, Journal Year: 2024, Volume and Issue: 100(7), P. 982 - 995

Published: May 8, 2024

The Organisation for Economic Co-operation and Development (OECD) Adverse Outcome Pathway (AOP) Programme is being explored in the radiation field, as an overarching framework to identify prioritize research needs that best support strengthening of risk assessment management strategies. To advance use AOPs, international horizon-style exercise (HSE) was initiated through Radiation/Chemical AOP Joint Topical Group (JTG) formed by OECD Nuclear Energy Agency (NEA) High-Level on Low Dose Research (HLG-LDR) under auspices Committee Radiological Protection Public Health (CRPPH). intent HSE key questions consideration development would help reduce uncertainties estimating health risks following exposures low dose dose-rate ionizing radiation. conducted several phases involving solicitation relevant questions, a collaborative review open-ended candidate elimination led selection 25 highest priority stated purpose.

The head of invasive cardiologists as a target of professional exposure to ionizing radiation

Published: Nov. 5, 2024

Exposure to ionizing radiation has recognized detrimental cancer and non-cancer health effects. These effects are now well-proven not only for high doses > 1,000 millisieverts (mSv) associated with head radiotherapy but also moderate (100–1,000 mSv) even low (< 100 doses, of interest professionally exposed cardiologists. The interventional cardiologists is highly radiation, possible damage the eye brain. Unprotected experience up ten times greater than chest below lead aprons, marked exposure left hemisphere brain reaching 2 Sv—equivalent 10,000 X-rays over a professional lifetime. This narrative review aims provide an overview background radioprotection, biological mechanisms involved, epidemiological evidence regarding in invasive include cataracts, cancer, cerebrovascular diseases, neurodegeneration, mood disorders. gathered from other populations, which experienced similar been reviewed. important because risks, consistent cases repeated exposures, occur more frequently patients, situations involving chronic as seen Despite these effective protective measures—such suspended ceilings, curtains, specialized eyewear—can reduce near-zero levels.
