Critical Care Clinics, 2005
The US Department of Homeland Security, and other state and federal agencies, continues to express concern over the potential use of radioactive isotopes as a weapon of terror. Few emergency medicine and critical care physicians are familiar with the care and treatment of an accidentally or intentionally irradiated patient who is contaminated ...

Radiation biology and radiation protection
Annals of the ICRP, 2012For protection purposes, the biological effects of radiation are separated into stochastic effects (cancer, hereditary effects) presumed to be unicellular in origin, and tissue reactions due to injury in populations of cells. The latter are deterministic effects, renamed ‘tissue reactions’ in the 2007 Recommendations of the International Commission on ...

Radiation Protection Dosimetry, 2011
When this paper was about to go to press, the International Commission on Radiological Protection released a statement recommending a change in the threshold dose for the eye lens and dose limits for eye for occupationally exposed persons. It is clear that the earlier published threshold for radiation cataract is no longer valid.

Nature, 1967
BETWEEN 1920 and 1935 a great deal was published on the subject of mitogenetic radiation - a radiation usually considered to be ultraviolet, which is emitted by dividing cells and which stimulates other cells to divide. These studies were originated by Gurwitsch1 and are still carried on in the Soviet Union, but almost ceased in Britain and the United ...

Obstetrical & Gynecological Survey, 1973
Irradiation during pregnancy may occur either as the result of radioactive pollution of the environment, or during a medical procedure using x-rays or radionuclides. While the former is usually unforeseeable, the latter is known and accepted by both physician and patient.Recent statistics estimate that about one quarter of pregnant women have had a ...

Nature, 1960
A discussion is presented of the view that whole-body irradiation of an animal can, in certain circumstances, speed up natural aging. In survival studies of chronically irradiated CBA mice, kept under certain conditions so that external disturbing factors were minimized, mean life shortening of a group of mice is roughly proportional to the mean ...

Microdosimetry and radiation quality determinations in radiation protection and radiation therapy
Radiation Protection Dosimetry, 2011Beams of different radiation qualities may, for equal absorbed dose, lead to important differences in the degree of harm for a specific biological endpoint. In many practical situations absorbed dose is then not a sufficient measure when for instance the same treatment result or risk level is the focus of attention.

To Radiate or Not to Radiate—The Challenges of Pelvic Reirradiation
Seminars in Radiation Oncology, 2020Patients who receive pelvic radiation are at risk for both local recurrences of their primary malignancy or for the development of a new malignancy in the irradiated pelvic structures. The management of postirradiation pelvic tumor is complicated and can be associated with both poor prognosis and significant morbidity.

Gamma ray is an energetic ionising radiation that can damage living cells as it slows down and transfers its energy to surrounding cells. Lead and concrete have been used as radiation shielding materials.

Radiation transport calculations for cosmic radiation
Annals of the ICRP, 2012The radiation environment inside and near spacecraft consists of various components of primary radiation in space and secondary radiation produced by the interaction of the primary radiation with the walls and equipment of the spacecraft. Radiation fields inside astronauts are different from those outside them, because of the body's self-shielding as ...
