beta radiation is divided into: Beta- and Beta+ radiations

Beta- radiation causes an atom to lose one neutron and gain one proton.
Hence, the atomic number is increased by 1 and (liczba masowa) is not changed.

Beta+ radiation causes an atom to lose one proton and gain one neutron.
Hence, the atomic number is decreased by 1 and (liczba masowa) is unchanged.

But, we can also take at a scope only single neutron or proton; not necessarily the whole atom. So:

Beta- radiation when in contact with isolated neutron causes it to transform into proton.

Beta+ radiation when in contact with isolated proton causes it to (surprise surprise) take no effect. Why?
Because mass of neutron is slightly higher (slightly w chuj, praktycznie identyczne).
So transition proton --> neutron is not possible, because mass cannot be increased without additional energy.

In an atom-scope proton --> neutron is possible, because the energy is taken from <jakieś tam atom binding idk>

---------

Energy released/absorbed by beta radiation is:

E = [delta masses] * c^2, where:

delta masses = Initial Atom mass - Final Atom mass - electron mass - neutrino(antineutrino) mass
c = speed of light

Beta radiation is directly related to half-life of an atom. (? chyba)
