Spectrometry was used by means of an alpha-radiometer on a [symbol: see text]porpecc-[symbol: see text] hard-and-software complex to study the radioactive contamination of the surfaces of neutralizers with plutonium 239-based ionizing radiation sources, which are employed to remove electrical charges from electrifiable materials. While using the neutralizers, the operating personnel is shown to be exposed to radiation. The level of removed radioactive contamination during half-a-year exploitation of the neutralizers was greater than the maximum allowable values on the average by several times. Radiation hazard in the use of radioisotopic neutralizers of static electricity is outlined.

Gafchromic Films as a Complementary In-field Dosimetric Tool to Monitor Low Photon Radiation Doses (≤50 mSv).
Health Phys
January 2025
Department of Physics, Toronto Metropolitan University, 350 Victoria Street, Toronto, Ontario, M5B 2K3.
This study elucidated the radiation response characteristics of a Gafchromic radiochromic film subjected to low photon doses of ≤50 mSv, which corresponds to the annual whole body effective dose limit for radiation workers in Canada. Radiochromic films are investigated for possible use as a complementary tool for the Canadian Armed Forces that can be worn in addition to their existing personal dosimetry to quickly assess personal radiation dose received from radiological hazards without reliance on electronics. The films were exposed to varying photon energies emanating from x-ray generators and radioisotopes, specifically cesium-137, cobalt-60, and americium-241.

Department of Genitourinary Radiation Oncology, The University of Texas MD Anderson Cancer Center, Houston, TX.
Background: To determine outcomes of MRI-assisted radiosurgery (MARS) for salvage brachytherapy using the radioisotope Pd after various upfront treatments including surgery, external beam radiotherapy, and brachytherapy.
Methods: We retrospectively reviewed data for patients who underwent salvage MARS for intraprostatic lesions or prostate bed recurrences from 2016 to 2022. Biochemical recurrence, prostate cancer-specific, and overall survival, and the cumulative incidences of toxicities, were determined by Kaplan-Meier estimates.
Measurement of natural radionuclides and health risk assessment in soil samples of the Main Central Thrust region in Garhwal Himalaya, India.

Department of Physics, H.N.B. Garhwal University, Badshahi Thaul Campus, Tehri Garhwal, 249199, India.
Ionizing radiation emitted from radionuclides is present everywhere in the environment. It is the main source of health hazards to the general public. The present study elaborates on the analysis of primordial radionuclides in the collected soil samples from the Main Central Thrust (MCT) region of Uttarakhand Himalaya in a grid pattern.

Clin Nucl Med
February 2025
From the Interventional Oncology/Radiology Service, Department of Radiology, Memorial Sloan Kettering Cancer Center, New York, NY.
Background: Radiation segmentectomy (RS) is an alternative potential local curative treatment for selected colorectal liver metastases (CLMs) not amenable to ablation or limited resection.
Purpose: The aim of this study was to evaluate the dosimetric response of low volume CLMs to RS in heavily pretreated patients who are not candidates for resection or percutaneous ablation.
Patients And Methods: This single-center retrospective study evaluated CLMs patients treated with RS (prescribed tumor dose >190 Gy) from 2015 to 2023.

Objective: assessment of probable exposure levels from radon and NORM in workplaces within the context of justi fying radiation protection plans in an existing exposure situation.
Materials And Methods: Materials regarding the assessment of naturally occurring radioactive material (NORM) con tent in tailing from mining and processing industries in Ukraine and assessments of contamination levels of industri al sites of oil and gas enterprises were used for estimating the probable range of effective doses (ED) of workers fromNORM at industrial enterprises. These materials were obtained as a result of research conducted by specialists from theRadiation Protection Laboratory of the State Institution «O.
