[Sterilization of cereal grain samples by gamma-irradiation (author's transl)]. 1974

D Di Maggio, and J Shejbal, and P M Dorello

With the aim of sterilizing cereal grain samples as to microfungal contamination, while causing possibly small changes in the qualitative characteristics, the effects of various doses of gamma-irradiation on slightly and strongly moulded soft wheat, and at low and high moisture contents, were studied. In order to obtain a satisfactory sterilization, high doses of greater than or equal to 1100 krad were needed, at which a noteworthy decrease of the germination energy and capacity was observed, while the main chemical parameters of wheat quality remained unaltered.

UI	MeSH Term	Description	Entries
D011830	Radiation Effects	The effects of ionizing and nonionizing radiation upon living organisms, organs and tissues, and their constituents, and upon physiologic processes. It includes the effect of irradiation on food, drugs, and chemicals.	Effects, Radiation,Effect, Radiation,Radiation Effect
D011839	Radiation, Ionizing	ELECTROMAGNETIC RADIATION or particle radiation (high energy ELEMENTARY PARTICLES) capable of directly or indirectly producing IONS in its passage through matter. The wavelengths of ionizing electromagnetic radiation are equal to or smaller than those of short (far) ultraviolet radiation and include gamma and X-rays.

D005720	Gamma Rays	Penetrating, high-energy electromagnetic radiation emitted from atomic nuclei during NUCLEAR DECAY. The range of wavelengths of emitted radiation is between 0.1 - 100 pm which overlaps the shorter, more energetic hard X-RAYS wavelengths. The distinction between gamma rays and X-rays is based on their radiation source.
