Low dose and low dose rate radioluminescence dosimetry.

open access: yesApplied Radiation and Isotopes, 2023
Review is provided of a number of low-dose, low dose rate situations that in study require advances in the development of dosimetric facilities. Using a clinical linac set up to provide doses down to the few mGy level, the performance of a real-time ...

High Dose-Rate Versus Low Dose-Rate Brachytherapy for Lip Cancer

open access: yesInternational Journal of Radiation Oncology*Biology*Physics, 2012
To analyze the outcome after low-dose-rate (LDR) or high-dose-rate (HDR) brachytherapy for lip cancer.One hundred and three patients with newly diagnosed squamous cell carcinoma of the lip were treated between March 1985 and June 2009 either by HDR (n = 33) or LDR brachytherapy (n = 70).

Postoperative management of keloids: low-dose-rate and high-dose-rate brachytherapy.

Brachytherapy, 2014
We report the experience of the Radiation Oncology Department of the European Institute of Oncology in Milan, Italy, on the adjuvant low-dose-rate (LDR) and high-dose-rate (HDR) interstitial brachytherapy. Brachytherapy might be useful to improve keloids recurrence rate or reduce keloids treatment side effects instead of external beam radiotherapy.Data

The OER at low dose-rates

The British Journal of Radiology, 1976
Interest in the treatment of human cancers with beam therapy at low dose-rates, with fractionation using multiple doses per day (Pierquin et al., 1974; Brown et al., 1974) and with the utilization of 252Cf neutrons at low dose-rates (Hall and Rossi, 1975) is steadily growing.

Self‐Powered X‐Ray Detector Based on All‐Inorganic Perovskite Thick Film with High Sensitivity Under Low Dose Rate

Physica Status Solidi (a), 2019
Hybrid perovskite materials have been one of the brightest spotlights in the radiation detection research fields due to their higher carrier mobility and lower trap state density in recent years.

Apoptosis induced by low-dose and low-dose-rate radiation

Cancer, 2002
It has been claimed that external radiation, as a treatment modality for malignant diseases, partly induces apoptosis. It is not known, however, whether therapeutic low-dose and low-dose-rate radiation are able to induce apoptosis.The effect of low-dose radiation on apoptosis induction in HeLa Hep2 cells was studied, and quantitation of the apoptotic ...

Low dose or low dose rate ionizing radiation-induced health effect in the human.

Journal of Environmental Radioactivity, 2018
The extensive literature review on human epidemiological studies suggests that low dose ionizing radiation (LDIR) (≤100 mSv) or low dose rate ionizing radiation (LDRIR) (

RISKS OF RADIATION AT LOW DOSE RATES

The Lancet, 1981
Cancer mortality has been studied in 1110 women who worked in the U.K. with paint containing radium from 1939 to 1961. Their body contents of radium were small, but they were also irradiated externally by gamma-rays to receive absorbed dose rates of 1-4 mGy per week.

Oxygen Radiosensitisation at Low Dose Rate

The British Journal of Radiology, 1985
Oxygen radiosensitisation has been studied at dose rates of 600, 3.37 and 0.89 Gy/h at pO2 levels of 0.001, 0.03, 0.1, 0.3, 1, 3, 10 and 21% in the gas phase. The oxygen enhancement ratio (OER), evaluated at 2% cellular survival, exhibited a decrease with dose rate from a value of 3.2 at the acute dose rate, to 2.4 at the lowest dose rate.
