Alpha (α) Radiation
The alpha radiations particles have 2 protons and 2 neutrons which are in a helium nucleus. As the alpha particles emit the helium nucleus the nucleus gives away the two protons and two neutrons. As a result of this the mass number will reduce by 4 and the atomic number will result in reducing by 2. This is known as alpha decay.
One source of alpha radiation could be plutonium 239. The alpha particles have many characteristics. First of all the alpha radiation has a helium nucleus. Also the penetrating power of alpha is very little. This means that it can’t go through everything. Despite this the range in air for the alpha particles is only few cm. however the alpha particles are very ionising. This means that they can …show more content…
The beta – plus radiation is one of the types of decay. The structure of a positron is where the proton of the beta- plus is found in the radionuclide. The nucleus then makes neutrons which then give out positrons which are beta- plus particles.
When the neutron transforms into a proton, the proton stays back in the nucleus and the electron that is formed moves away with a lot energy. As the beta –plus particle emits the nucleus, it results in the nucleus changing and gaining one extra proton and losing one neutron.
The atom that can be used in beta – plus is carbon 11. The other term that can be used to say beta – plus radiation is positron emission. The beta – plus radiation has many different characteristics. First of all the penetrating power is okay. However this radiation can be absorbed by everything. Also the range of air for this type of radiation is few mm (millimetres). This means that the radiation can only travel a few mm (millimetres). However the ionisation for beta – plus is very poor. This means that it can use electrons to transform in to charged particles.
Beta – minus (β-) …show more content…
The only difference is that the beta – minus has a negative charge. When the nucleus emits the beta – minus radiation particles, the nucleus end up having the same quantity of protons and neutrons inside it. As a result of this one of the neutron particles turns to become a proton and electron particle. The proton that is made stays behind with the nucleus. However the electron that is also made gets emitted.
The beta – minus radiation is an electron. The most common element that can be used in beta – minus particles is strontium 19. The first characteristic of the beta – minus radiation is that the penetration power is really good. This means that it can go through a lot of things. However the thing that absorbs this radiation is aluminium. Also the range in air is few metres. His means the beta- minus radiation can travel few metres. However the ionisation is relatively low. This means that the beta- minus radiation don’t collide with
