Radiology, 1946
Webster defines the word “dose” as “the measured quantity of medicine to be taken at one time or in a given period of time; a definite quantity or portion, usually small, of anything regarded as having a remedial or beneficial influence.” “Dosage” is defined as “the administration of medicine in doses, especially in graded doses, according to age, etc.“

Absorbed radiation dose in radiation synovectomy
The British Journal of Radiology, 1978The intra-articular injection of colloids containing β-particle emitting radionuclides has been shown to help in controlling synovial inflammation in a range of joints (Ansell et al., 1963; Grahame et al., 1970; Gumpel, 1973; Menkes et al., 1977), and in the knee Gumpel and Coles (1975) have shown the technique to be the treatment of choice for the ...

Radiation dose in neuroradiological procedures
Neuroradiology, 1978Radiation dose is cumulative in the radiosensitive organs. In neuroradiology the organ of particular interest is the eye. There is an immutable physical relationship between spatial resolution, signal-to-noise ratio (i.e., density discrimination), and dose: Dose alpha (formula: see text).

Health Physics, 1958
This paper considers the influence of phantom geometry on the dose, particularly the maximum dose, within the phantom. It is shown that the maximum dose within an irradiated convex phantom cannnot exceed the maximum dose in a slab similarly irradiated and thus maximum doses computed for slabs supply upper estimates of doses for many phantoms. The first

Radiation risk is linear with dose at low doses
The British Journal of Radiology, 2005This paper presents a brief argument, based on a mechanistic approach, to show that radiation risk is linear with radiation dose from zero dose up. Similarities in cellular effects lead to the assumption of a common mechanism and the DNA double strand break is identified as the crucial radiation-induced lesion.

Dose and dose rate effectiveness of space radiation
Radiation Protection Dosimetry, 2006Dose and dose rate effectiveness factors (DDREF), in conjunction with other weighting factors, are commonly used to scale atomic bomb survivor data in order to establish limits for occupational radiation exposure, including radiation exposure in space. We use some well-known facts about the microscopic pattern of energy deposition of high-energy heavy ...

Painting Dose: The ART of Radiation
International Journal of Radiation Oncology*Biology*Physics, 2016The discovery of X rays in 1895 captivated society like no other scientific advance. Radiation instantly became the subject not only of numerous scientific papers but also of circus bazaars, poetry, fiction, costume design, comics, and marketing for household items.

Radiation dose in dental radiology
European Radiology, 2002The aim of this study was to compare radiation exposure in panoramic radiography (PR), dental CT, and digital volume tomography (DVT). An anthropomorphic Alderson-Rando phantom and two anatomical head phantoms with thermoluminescent dosimeters fixed at appropriate locations were exposed as in a dental examination.

Annals of the ICRP, 2012
Practical implementation of the International Commission on Radiological Protection's (ICRP) system of protection requires the availability of appropriate methods and data. The work of Committee 2 is concerned with the development of reference data and methods for the assessment of internal and external radiation exposure of workers and members of the ...
