Alpha Beta and Gamma Radiation Lab
ثبت نشده
چکیده
Unstable atomic nuclei may decay into less energetic nuclei by emission of alpha, beta, and gamma radiation. These forms of radiation are now known to consist of He4 nuclei, electron (or positron), and high energy photons respectively. Which types of decay a nuclei may undergo depends on how it is unstable. Many materials may emit more than one form of radiation. This is especially true when the original parent radioactive nuclei produce daughter nuclei that are also radioactive. Such decay chains will be investigated further in one of the next labs, Airborn Radiation: The Radon Decay Chain. In such cases the various forms of radiation can be separated by a magnetic field as shown in Figure 1.

Conceptual Design and Simulation of Alpha-Beta Detector for Surface Contamination Measurements
The radioactive contamination measurement is essential in nuclear facilities. Monitoring of low level alpha and beta contamination is possible using light detectors high efficiency. Due to the fact that many detectors canchr('39')t simultaneously discriminate alpha, beta and gamma rays; among existing methods, phoswich detectors would be appropriate option to measure different radioactive conta...
متن کاملAnti-inflammatory role of piperine against rat lung tissue damage induced by gamma-rays
Background: Radiation‐induced acute lung damages are refractory side effects in lung cancer radiotherapy (RT). Prospective study investigates the possible role of piperine (Pip) as anti-inflammatory agent against γ-rays-induced lung tissue lesions in an applicable rat model. Materials and Methods: Fifty-six Sprague-Dawley rats were divided into four groups: Control, rats were administered...

This paper consider the general forms of $(alpha,beta)$-fuzzyleft ideals (right ideals, bi-ideals, interior ideals) of an orderedsemigroup, where$alpha,betain{in_{gamma},q_{delta},in_{gamma}wedgeq_{delta}, in_{gamma}vee q_{delta}}$ and $alphaneqin_{gamma}wedge q_{delta}$. Special attention is paid to$(in_{gamma},ivq)$-left ideals (right ideals, bi-ideals, interiorideals) and some related pr...
متن کاملA fixed point method for proving the stability of ring $(alpha, beta, gamma)$-derivations in $2$-Banach algebras
In this paper, we first present the new concept of $2$-normed algebra. We investigate the structure of this algebra and give some examples. Then we apply a fixed point theorem to prove the stability and hyperstability of $(alpha, beta, gamma)$-derivations in $2$-Banach algebras.
