Typical doses and dose rates in studies pertinent to radiation risk inference at low doses and low dose rates [PDF]

Journal of Radiation Research, 2018
In order to quantify radiation risks at exposure scenarios relevant for radiation protection, often extrapolation of data obtained at high doses and high dose rates down to low doses and low dose rates is needed. Task Group TG91 on 'Radiation Risk Inference at Low-dose and Low-dose Rate Exposure for Radiological Protection Purposes' of the ...

Evaluation of DNA damage and stress in wildlife chronically exposed to low-dose, low-dose rate radiation from the Fukushima Dai-ichi Nuclear Power Plant accident

Environment International, 2021
The health effects associated with chronic low-dose, low-dose rate (LD-LDR) exposures to environmental radiation are uncertain. All dose-effect studies conducted outside controlled laboratory conditions are challenged by inherent complexities of ...

Low‐dose‐rate brachytherapy for prostate cancer: A 15‐year experience in Japan

International journal of urology, 2020
The history of prostate brachytherapy has passed one century. In 1983, modern low‐dose‐rate prostate brachytherapy using a transrectal ultrasound‐guided procedure was introduced.

Radiation dose rate effects: what is new and what is needed?

Radiation and Environmental Biophysics, 2022
Despite decades of research to understand the biological effects of ionising radiation, there is still much uncertainty over the role of dose rate.

Seed Density as a New Predictive Index of Seed Migration in Brachytherapy for Prostate Cancer Using Iodine-125 Loose Seed

Current Oncology, 2023
Aim: This study aimed to examine the usefulness of seed density as a predictor of seed migration in patients with prostate cancer who received brachytherapy using Iodine-125 loose seed.

Absence of a dose-rate effect in the transformation of C3H 10T1/2 cells by α-particles [PDF]

, 1987
The findings of Hill et al. (1984) on the greatly enhanced transformation frequencies at very low dose rates of fission neutrons induced us to perform an analogous study with -particles at comparable dose rates. Transformation frequencies were determined

Immunological and hematological outcomes following protracted low dose/low dose rate ionizing radiation and simulated microgravity

Scientific Reports, 2021
Using a ground-based model to simulate spaceflight [21-days of single-housed, hindlimb unloading (HLU) combined with continuous low-dose gamma irradiation (LDR, total dose of 0.04 Gy)], an in-depth survey of the immune and hematological systems of mice ...

New Concerns for Neurocognitive Function during Deep Space Exposures to Chronic, Low Dose-Rate, Neutron Radiation

eNeuro, 2019
As NASA prepares for a mission to Mars, concerns regarding the health risks associated with deep space radiation exposure have emerged. Until now, the impacts of such exposures have only been studied in animals after acute exposures, using dose rates ∼1 ...
