Optimal KI Prophylactic Dose Determination for Thyroid Radiation Protection After a Single Administration in Adult Rats

Dose-Response, 2017
A dose–response study was performed in adult rats to select an optimal stable potassium iodide (KI) dose which could be implemented in repeated prophylaxis, in case of prolonged exposure to radioactive iodine.

PIN Photodiodes for Radiation Monitoring and Protection in the BaBar Silicon Vertex Tracker [PDF]

Int.J.Mod.Phys. A16S1C (2001) 1084-1086, 2000
We discuss the design, implementation and performance of the radiation monitoring and protection system used by the Silicon Vertex Tracker (SVT) in the BaBar detector. Using 12 reverse-biased PIN photodiodes mounted around the beampipe near the IP, we are able to provide instantaneous radiation dose rates, absorbed dose integrals, and active protection

Activity of natural radionuclide 210Pb in different foodstuffs in the Czech Republic and its annual intake

Czech Journal of Food Sciences, 2019
Activities of 210Pb in 18 sorts of foodstuffs were determined by radiochemical analysis. The lowest activity was found in carrots (0.01 Bq/kg) and cabbage (0.03 Bq/kg), the highest in banana (1.54 Bq/kg).

Patient‐specific adaptive planning margin for whole bladder radiation therapy

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background Whole bladder irradiation is an organ preservation treatment approach for muscle‐invasive bladder cancer (MIBC). Conventional planning margins, typically 15–20 mm, increase normal tissue toxicity and limit possible dose escalation.

Evaluation of AI‐based auto‐contouring tools in radiotherapy: A single‐institution study

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background Accurate delineation of organs at risk (OARs) is crucial yet time‐consuming in the radiotherapy treatment planning workflow. Modern artificial intelligence (AI) technologies had made automation of OAR contouring feasible. This report details a single institution's experience in evaluating two commercial auto‐contouring software ...

The implications of the American Board of Radiology's decision to relinquish its specialty board designation on prospective authorized medical physicists (AMPs) and radiation safety officers (RSOs)

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract In order to independently supervise the medical use of byproduct material, physicists in the United States (US) must legally meet the qualifications defined by the Nuclear Regulatory Commission (NRC) in the 35th part of the tenth title of the Code of Federal Regulations (§ 10 CFR Part 35). The American Board of Radiology (ABR) relinquished its
