Sensitometry of the response of a new radiochromic film dosimeter to gammaradiation and electron beams. The method consists in measuring the intensity of gammaradiation emitted from a source foil after passing through an absorber foil. In one specific case studied, the optical activity was enhanced by the gammaradiation, yielding a polymer that could act as a template for prebiotic chemistry. Our running example's geometry consists of a sheet of carbon steel with an aluminum half sphere shell on top of it, and a gammaradiation source just above its center. The most common predictive method uses a gammaradiation sensor to estimate the coal depth by exploiting the radioactivity of host strata typically found with coal deposits. Gammaradiation will cover a very wide area, with grave danger to those who are not protected, perhaps up to one-and-three-quarter or two miles.

Contains Parliamentary information licensed under the Open Parliament Licence v3.0 No respirator can give protection against this external gammaradiation. From the Hansard archive Example from the Hansard archive. Contains Parliamentary information licensed under the Open Parliament Licence v3.0 I am not sure whether that would be a gammaradiation or an alpha one. From the Hansard archive Example from the Hansard archive. Contains Parliamentary information licensed under the Open Parliament Licence v3.0 It reached only to gammaradiation and not the more dangerous beta radiation. From the Hansard archive Example from the Hansard archive. Contains Parliamentary information licensed under the Open Parliament Licence v3.0 No; the term "gamma" refers to external exposures to gammaradiation. From the Hansard archive Example from the Hansard archive. Contains Parliamentary information licensed under the Open Parliament Licence v3.0 It also emits small amounts of beta and gammaradiation, which have a higher penetrative power. From the Hansard archive Example from the Hansard archive. Contains Parliamentary information licensed under the Open Parliament Licence v3.0 The gamma dose rate is a measure of the quantity of gammaradiation over a fixed period. From the Hansard archive Example from the Hansard archive. Contains Parliamentary information licensed under the Open Parliament Licence v3.0 Direct, immediate radiation occurs at the moment of explosion in the form of gammaradiation. From the Hansard archive Example from the Hansard archive. Contains Parliamentary information licensed under the Open Parliament Licence v3.0 The most direct hazard is from gammaradiation which can both cause cancer and induce genetic defects in future generations.
