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.

Stereolithographic modelling and radiation dosage

British Journal of Oral and Maxillofacial Surgery, 2003
Hughe’s paper1 highlights the use of stereolithographic models to facilitate custom-made titanium prosthesis for simple orbital floor reconstructions. In more complex orbital, defects mirror imaging the normal orbit can be helpful in determining the correct shape and volume of the damaged orbit.2 The benefits of these techniques must be weighed against

Radiation Dosage Planning and Dosage Calculation

Radiology, 1952
In radiation therapy it is generally appreciated that tumor effect is dependent on tumor dose, and on the total time during which this dose is administered. For a particular patient and series of treatments, determination of tumor dose requires the following procedures: 1.

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.

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.
