An Attempt to Reduce the Background Free Radicals in Fingernails for Monitoring Accidental Hand Exposure of Medical Workers

Applied Sciences, 2020
While it is recognized that some medical workers could receive significantly higher radiation doses to their hands than the routinely monitored personal doses, accurate retrospective dosimetry of their hand exposure is still challenging.

Potential Use of Environmental Biological Samples for Retrospective Electron Paramagnetic Resonance Dosimetry of Radiation Accidents

Applied Sciences, 2020
Retrospective dosimetry is one of the most important tools of accident dosimetry for environmental dose estimation when large-scale radiological incidents and nuclear mass-casualty events occur.

99mTc-macroaggregated albumin SPECT/CT predictive dosimetry and dose-response relationship in uveal melanoma liver metastases treated with first-line selective internal radiation therapy

Scientific Reports, 2023
First-line selective internal radiation therapy (SIRT) showed promising outcomes in patients with uveal melanoma liver metastases (UMLM). Patient survival depends on liver’s disease control. SIRT planning is essential and little is known about dosimetry.

Dosimetry during adjuvant 131I therapy in patients with differentiated thyroid cancer-clinical implications

Scientific Reports, 2021
The activity of radioiodine (131I) used in adjuvant therapy for thyroid cancer ranges between 30 mCi (1.1 GBq) and 150 mCi (5.5 GBq). Dosimetry based on Marinelli's formula, taking into consideration the absorbed dose in the postoperative tumour bed (D ...

Rectal and Bladder Dose Measurements in the Intracavitary Applications of Cervical Cancer Treatment with HDR Afterloading System: Comparison of TPS Data with MOSFET Detector [PDF]

Journal of Biomedical Physics and Engineering, 2020
Background: Intracavitary brachytherapy plays a major role in management of cervical carcinoma. Assessment of dose received by OAR’s therefore becomes crucial for the estimation of radiation toxicities in HDR brachytherapy.

The effects of age and other individual factors on radiation induced ESR signals from fingernails

Frontiers in Public Health
Biodosimetry is crucial for assessing ionizing radiation exposure to guide medical responses. Electron spin resonance (ESR) spectroscopy using fingernails can be effectively used for both occupational and public dose assessments in radiological accidents

Investigation of post-therapeutic image-based thyroid dosimetry using quantitative SPECT/CT, iodine biokinetics, and the MIRD’s voxel S values in Graves’ disease

EJNMMI Physics, 2020
Background Before radioiodine therapy for Graves’ disease, the estimated thyroid-absorbed dose is calculated based on various clinical parameters. However, the actual accumulation of iodine in the thyroid during radioiodine therapy is not determined.

Current Evidence on Best Practice Dental Survivorship Care for People With Head and Neck Cancer: An Overview of Systematic Reviews and Emerging Evidence

Head &Neck, EarlyView.
ABSTRACT Introduction Head and neck cancer (HNC) survival is improving, increasing the need to address long‐term survivorship issues. Dental survivorship—care before, during, and after treatment—remains inconsistent across services. We conducted a review of systematic reviews and emerging evidence to inform contemporary dental survivorship care for HNC
