e) Distinguish between the following: a rays and ß rays
Answers
Answer:
Radioactivity is the act of emitting radiation spontaneously and is done by an atomic nucleus (unstable) to attain a more stable configuration by giving up some energy. Radioactivity is a physical, but not a biological phenomenon.
Therefore, during radioactivity three major types of radiations are emitted by the radioactive particles namely alpha, beta, and gamma. From the nucleus of an atom, these radiations are released and their behaviours are different from one another. But all three radiations cause some ionization and have some penetration power.
About Alpha Rays
Alpha rays are positively charged. They are highly active and energetic helium atoms consisting of two neutrons and two protons. Its symbol is α. These alpha particles are often released from the nucleus of a radioactive atom. Alpha particles are excreted in the alpha decay process.
These particles have the lowest penetration power and the highest ionization power. Due to their high ionization power, they can cause serious damage if they get into the body. These particles are emitted into "proton-rich" atoms.
