Clinical Radiation Dosage

The British Journal of Radiology, 1949
A clinical unit of radiation dosage (the rec or rontgen equivalent clinical) based on the rontgen under standard treatment conditions, is described. The relative biological effects of specific ion-density, over-all time, and field size are calculated so that equivalent dosage can be obtained under all treatment conditions.

Radiation Dosage to Medical Personnel

American Industrial Hygiene Association Journal, 1960
A survey was made to evaluate exposure to those physicians and dentists employing radiation. Many medical personnel other than radiologists employ radiation such as the general practitioner, surgeon, urologist, and the dentist. It is emphasised that among the various specialty groups varied factors of kilovoltage, current filter, technique, etc., will ...

Radiation Dosage in Tinea Capitis

Archives of Otolaryngology, 1977
To the Editor.—In his paper on "Radiation-Induced Salivary Gland Tumors," which appeared in the September issue of Archives (102:561-562, 1976), Dr Smith referred to our study of Israeli children irradiated for tinea capitis. He reported that these children received 1,750 to 2,000 rads to the head, which is not accurate.

Reducing the radiation dosage in patients with a scoliosis

International Orthopaedics, 1989
A significant number of girls develop an adolescent idiopathic scoliosis and require repeated full-length radiographs of the spine. Since Nash's publication in 1979 [16], there has been considerable concern expressed about protecting them from excessive radiation, and particularly from the development of radiation-induced breast tumours.

PERSONAL DIARY OF RADIATION DOSAGE

Journal of the American Medical Association, 1951
I. PERSONAL RADIATION DIARIES This is a plea for the adoption of a nationally standardized personal radiation-diary system. The purpose of such a system would be to reduce to a readied exactness the composite previous irradiation record of any individual patient.

Dosage in Radiation Therapy

The British Journal of Radiology, 1935
There are two distinct aspects from which the subject of dosage in radiation therapy can be regarded. The first is the physical aspect concerned with the accurate measurement of and statement of dosage. The second is the purely clinical aspect concerned with the determination of the appropriate doses required in actual clinical practice.

Dosage Units for High-Energy Radiation

Radiology, 1950
The study of radiation dosage measurement began twenty-five years ago with the main problem of establishing a system of x-ray dosage. It has been extended in recent years to many other types of radiation. It is important for us today to appreciate the fact that originally the establishment of a unit and method of x-ray dosage was thought to be, or ...

Thermoluminescence, low radiation dosage and black-body radiation

Physics in Medicine & Biology, 1967
It is shown that the emission of quanta in the visible region by the heating unit of a thermoluminescence reader is a major source of spurious signal in observations of low radiation dosage. At a heater temperature of 300 degrees C, about 120 photoelectrons per second are emitted from an S11 photomultiplier cathode for a typical reader construction.
