Neutrons and X-rays are used to investigate basic physical and biological processes. This chapter describes some of these important applications of radiation. Diseases such as cancer can be treated by gamma rays. Food spoilage is reduced greatly by irradiation. Medical supplies are rendered sterile ...
A physicist at the University of California, Riverside, has performed calculations showing hollow spherical bubbles filled with a gas of positronium atoms are stable in liquid helium. The calculations take scientists a step closer to realizing a gamma-ray laser, which may have appl...
Radiation-induced mutations from accessory buds of sweet cherry, Prunus avium L. cv ‘Bing’ Dormant scions of ‘Bing’ were exposed to 1–2.5 krad of gamma radiation in order to induce useful mutations. The main buds were excised and the scions gr... SSM Thompson - 《Tag Theoretical & ...
Such approaches include addition of deodorizing agents, chemical sterilization, using either gaseous or liquid sterilization agents, microwave sterilization, and irradiation sterilization with, e.g., sufficiently energetic gamma rays to kill biological organisms originally present in the waste materials. ...
Examples of ionized particles which may be detected with devices of this structure are high energy photons, electrons, X-rays and ionized particles are characteristic of X-rays, beta particles and ionized particles are characteristic of gamma radiation. Applications of the Invention The invention ...
Radiation in the form of gamma rays, beta particles, and neutrons is being used in science and industry to achieve desirable changes. Radiation doses control offending organisms including harmful bacteria and cancer cells and sterilize or kill insects. Local energy deposition can also stimulate ...
