We limited this study to use of the 6-MV beam with which photons comprise the principal component of scatter radiation. However, at higher radiation levels above 18 MV, neutrons also start playing ...

Note: Listed are all patients with implanted cardiac devices undergoing radiation therapy at the Mayo Clinic–Rochester between 2002 and 2007. Of 13 patients, 12 had their devices interrogated ...

In some examinations the operator may be present in the scanning room; thus the scattered radiation from the total annual patient workload must be considered when assessing occupational dose levels.

Thyroid collars should be used in all examinations where the thyroid may be exposed to the main beam or to a considerable amount of scatter radiation. Lead aprons must be provided for a person who is ...

the scattering of light by particles that are much smaller than the wavelength of radiation. Here's a second component to ...
