In medical x-ray departments, industrial facilities and nuclear reactors, local radiation was measured with film dosimeters in more than 1700 different places. These were fixed over a period of about 30 days in different spots of the controlled rooms. The obtained measurements are classified into different groups. The advantage of film dosimeters compared with usual measurements of the dose rates is the fact that they give an average of the real dose over a period of time at low cost. The obtained results are of interest for radioprotection technique.

A Prospective Study of a Custom-Made Eco-Friendly Thyroid Shield: A Breakthrough in Radiation Protection.

Department of Oral Medicine and Radiology, Drs Sudha and Nageswara Rao Siddhartha Institute of Dental Sciences, Vijayawada, IND.
Background The thyroid gland is the most susceptible organ to radiation during the exposure of teeth because the thyroid area appears to be within the primary beam, and the dose levels are relatively high even after using collimation. This study aims to develop an eco-friendly thyroid shield by reusing lead foils from intra-oral periapical radiographic films and evaluate its effectiveness in intraoral radiography. Methods A total of 16 patients undergoing endodontic procedures who gave written consent to participate in the study were included and divided into four categories: anterior, canine, premolar, and molar.

Purpose: Due to the extensive use of radiation in various fields, such as food safety, sterilizing surgical materials, and medical diagnostics, it is essential to minimize radiation exposure for both patients and healthcare professionals, even at low doses. To meet this requirement, a composite film has been developed using polyvinyl alcohol (PVA) polymer and nitro blue tetrazolium (NBT) dye to measure low radiation doses effectively.
Methods: Various concentrations of NBT dye (ranging from 0.
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.

Purpose: In vivo dosimetry is a common requirement to validate dose accuracy/uniformity in total body irradiation (TBI). Several detectors can be used for in vivo dosimetry, including thermoluminescent dosimeters (TLDs), diodes, ion chambers, optically stimulated luminescent dosimeters (OSLDs), and film. TLDs are well established for use in vivo but required expertise and clinical system availability may make them impractical for multifractionated TBI.

Purpose: Acute radiation dermatitis (ARD) is a notable challenge for patients with breast cancer undergoing postmastectomy radiation therapy (RT). This study evaluates the efficacy, safety, and user experience of StrataXRT versus Mepitel Film for ARD prevention.
Methods And Materials: This multicenter, noninferiority trial involved intrapatient randomization of 44 patients with histologically confirmed breast carcinoma who had undergone postmastectomy RT across 4 Australian hospitals from January 1 to December 31, 2017.
