Radiation Dose‐Volume Effects for Liver SBRT [PDF]

International Journal of Radiation Oncology*Biology*Physics, 2021
Stereotactic body radiation therapy (SBRT) has emerged as an effective, noninvasive treatment option for primary liver cancer and metastatic disease occurring in the liver. Although SBRT can be highly effective for establishing local control in hepatic malignancies, a tradeoff exists between tumor control and normal tissue complications.

Radiation Dose–Volume Effects in Radiation-Induced Rectal Injury [PDF]

International Journal of Radiation Oncology*Biology*Physics, 2010
The available dose/volume/outcome data for rectal injury were reviewed. The volume of rectum receiving >or=60 Gy is consistently associated with the risk of Grade >or=2 rectal toxicity or rectal bleeding. Parameters for the Lyman-Kutcher-Burman normal tissue complication probability model from four clinical series are remarkably consistent, suggesting ...

Dose-rate effects in radiation biology and radiation protection [PDF]

Annals of the ICRP, 2016
Quantification of biological effects (cancer, other diseases, and cell damage) associated with exposure to ionising radiation has been a major issue for the International Commission on Radiological Protection (ICRP) since its foundation in 1928.

Further Characterization of the Mitigation of Radiation Lethality by Protective Wounding [PDF]

, 2017
There continues to be a major effort in the United States to develop mitigators for the treatment of mass casualties that received high-intensity acute ionizing radiation exposures from the detonation of an improvised nuclear device during a radiological

Radiation Dose–Volume Effects in the Lung [PDF]

International Journal of Radiation Oncology*Biology*Physics, 2010
The three dimensional dose/volume/outcome data for lung are reviewed in detail. The rate of symptomatic pneumonitis is related to many dosimetric parameters, and there are no evident threshold “tolerance dose/volume” levels. There are strong volume and fractionation effects.

First-in-man evaluation of 124I-PGN650: A PET tracer for detecting phosphatidylserine as a biomarker of the solid tumor microenvironment [PDF]

, 2017
Purpose: PGN650 is a F(ab′) 2 antibody fragment that targets phosphatidylserine (PS), a marker normally absent that becomes exposed on tumor cells and tumor vasculature in response to oxidative stress and increases in response to therapy.

Natural Radiation Dose and Geomagnetic Effect

Journal of Geoscience and Environment Protection, 2018
Earth keeps getting bombarded by high-energy particles that originate in the outer space and in Sun. Cosmic radiation in Earth’s atmosphere consists of a photon and directly ionizing component and a neutron component. Charged particles of cosmic radiation are deflected by the geomagnetic field that is more expressed at the equator than near the poles ...

Investigation of Natural Effective Gamma Dose Rates case study: Ardabil Province in Iran [PDF]

Gamma rays pose enough energy to form charged particles and adversely affect human health. Since, the external exposure of human beings to natural environmental gamma radiation normally exceeds that from all man-made sources combined, natural background ...
