6.3.1.4 Gamma ray logs Certain elements show nuclear disintegration by emitting energy in the form of alpha, beta, and gamma particles. Alfa particles are helium nuclei and beta particles are electrons. Both of these have relatively low penetrating power and are stopped by a small thickness of ...
gamma ray A stream of electromagnetic radiation having wavelengths shorter than those of x-rays and therefore greater energy and penetrating power. Gamma rays are given off by unstable nuclei during radioactive decay. ♦ The emission of gamma rays by a nucleus is calledgamma decay. Gamma decay...
Beta-rays are electrons and also have only a low penetrating power.doi:10.1007/978-94-011-0551-4_5R. HalmshawSpringer Netherlands
Gamma ray, electromagnetic radiation of the shortest wavelength and highest energy. Gamma rays are produced in the disintegration of radioactive atomic nuclei and in the decay of certain subatomic particles. It includes some overlap with X-rays in the el
Gamma radiation has great penetrating power—that is, it can go through matter of great thickness without appreciable attenuation. The main processes that take place upon the interaction of gamma radiation with matter are photoelectric absorption (the photoelectric effect), Compton scattering (the Compto...
they are produced by the decay of nuclei as they transition from a high energy state to a lower state. Since the gamma rays are in substance only very high-energy photons, they are very penetrating matter and are thus biologically hazardous. Gamma rays can travel thous...
The bremsstrahlung process is the same mechanism that is exploited to produce x-rays in the common x-ray tube. The energy of the electrons and positrons released in nuclear reactors is generally too low to produce penetrating bremsstrahlung, and it is not usually worthwhile considering it as a...
Because gamma rays are energy and not matter, they are very penetrating and can cause damage to animal and plant tissues. Gamma rays are absorbed by extremely dense materials like lead (Pb) and depleted uranium (U).Gas A substance of very low density that has no definite shape or volume....
There are three types of nuclear radiation: alpha, beta and gamma.Alpha is theleast penetrating, while gamma is the most penetrating. What is the most penetrating type of radiation? Gamma radiationis the most penetrating of the three radiations. It can easily penetrate body tissue. It requires...
The Bremsstrahlung from high power electron accelerators provides an intense source of penetrating radiation for industrial processing. Applications includ... JPJ Farrell - 《Nuclear Science IEEE Transactions on》 被引量: 13发表: 1981年 THE RELATION BETWEEN COSMIC $gamma$-RAYS AND SYNCHROTRON X-RAYS ...
