In this section, we will describe different types of software testing. Various types of software testing are performed to achieve different objectives when testing a software application. You can also read about different Software Testing Techniques which can be associated with various types of software testing.

Alpha particles are helium nuclei, containing two positively charged protons and two neutrally/zero charged neutrons, and therefore have an overall charge of 2+. Protons and neutrons each have a mass of 1 atomic mass unit, and so an alpha particle has a total mass of 4. This high mass of an alpha particle explains how they interact with the human body. They are large and heavy particles and so tend to move slower than other kinds of dangerous radiation. However, because of their large mass, when they do collide with human tissue, they cause more damage.
