Medical radiation workers constitute the largest group occupationally exposed to 
man‑made ionizing radiation, yet much evidence on cancer risk derives from early 
high‑dose practice eras that differ substantially from current con...

Clinical justification remains fundamental to the safe use of imaging involving ionising radiation, requiring a favourable balance between diagnostic benefit and stochastic risk. Concurrently, advances in imaging technology and artificial i...
Survey of safety practices of laser and non-laser optical radiation sources used in aesthetic laboratories in Greece [0.03%]
希腊美容实验室中激光和非激光光学辐射源安全实践调查
Aspasia Petri,Maria Karatsalioti,Mirofora Pilakouta et al.
Aspasia Petri et al.
The use of non-ionizing radiation for aesthetic purposes is steadily increasing, with aesthetic laboratories frequently employing lasers, IPL, UV, and LED devices. In Greece, as in many countries, no regulatory framework exists to ensure th...
Shielding Performance and Clinical Applicability of Lead-Free Materials in Computed Tomography [0.03%]
无铅材料在计算机断层扫描中的防护性能及其临床应用价值

Backscatter factor (BSF) is a critical correction parameter in radiation dosimetry, accounting for dose enhancement due to photon scattering within irradiated media; however, systematic evaluations beyond the ISO slab phantom remain limited...
Model-Based Evaluation of Point-Source Approximation Error for Extended Radionuclide Sources in Nuclear Medicine [0.03%]
核医学中扩展放射源点源近似误差的模型评估方法研究
Rhodri Smith,Bill Thomson,Hannah Nelstrop et al.
Rhodri Smith et al.
Accurate estimation of external radiation exposure is essential in nuclear medicine (NM) for occupational safety and regulatory compliance. Point-source models are widely used because they are simple and require limited input data; however,...
Radiological Clearance at CERN: Classical Machine Learning Methods for Waste Classification [0.03%]
基于传统机器学习方法的放射性废物分类及在欧洲核子研究组织中的应用
Andrea Gomes,Matteo Magistris,Maria Elisso Stamati et al.
Andrea Gomes et al.
At CERN, the maintenance and dismantling of high-energy particle accelerators generate waste that is potentially radioactive. When activity levels are negligible, waste can be released from regulatory control through clearance procedures. H...
From Fragmentation to Integration: Building a Globally Harmonized Biodosimetry Framework for Radiological Emergency Preparedness [0.03%]
