Basic Modes of Radioactive Decay

Abstract

This basic modes of radioactive decay review “ Gamma Rays ” reviews some topics related to radiation, its classification and importance. In general, gamma rays interfere with our life, so we need to comprehend radiation as fact around us all the time and all the time. We live in a naturally radioactive world, but to what extent do physicians, nurses, and medical technicians, who may have to deal with urgent cases of a radiation, know about it? This chapter will address what radiation is and what is its role. This chapter will guide us toward the knowledge of ionizing radiation and its certain forms such as alpha particles, beta particles, gamma rays, and X-rays. as well as it will review on radioactive decay (nuclear decay) as well as help us learn about radioactivity and radiation, in addition to the types of decays, which are divided into beta decay, gamma decay, electron capture, positron decay, and alpha decay. This chapter will focus on radioactive decay, the activity and units of radioactive activity, and half-life of it. The last part of this chapter discusses attenuation as the reduction in the intensity of gamma ray or X-ray beam. The most important subtitles that are scattered from attenuation are HVL mean free path, the linear attenuation coefficient, pair production, and photoelectric scattering.
