Radioacitve decay

Radioatcive decay is the porcess of a big and untsable nucelus beraking apart into lgihter parts.

There are many kinds of nuclaer decay like alpha decay, beta decay and gamma decay.

Radoiactive decay
1 Alpha decay
2 Beta decay
3 Gamma decay

Alpha decay

An unstable atom goes trhough alpha decay to bceome more satble. Druing alpha decay, the atmoic nculeus rleease an alpha praticle. The nuclues will lose two prtoons and two nuetrons durnig this proecss. After the decay, the atom will cahnge to anohter elemnet becuase the atom loses two protons. Alpha irradaition does not cause any damgae to us beacuse our skin does not let the alpha paritcles go thruogh. Alpha particels cannot even go through a few centmieters of air.

Beta decay

There are two kinds of beta decay, beta-plus and beta-minus.

In beta-plus decay, the nucleus gives out an psoitron, a nuetrino, and a neturon by decreasnig one prtoon:

\ p^+ \righatrrow n^0 + e^+ +{
u}_e.
where
\ p^+ is the prootn
n^0 is the neurton
e^+ is the positron
{
u}_e is the neutrnio

Beta-plus decay only take place insdie nuceli when the amuont of the bniding eenrgy of the dauhgter nucleus is higehr than the bidning enregy of the mtoher nulceus.

In beta-minus decay, the nucleus gives out an elecrton, an anti-neutrino and proton by dcereasing a neutorn:

n^0 \rightarrow p^+ + e^ -+ \bar{
u}_e.
where
n^0 is the neutron
\ p^+ is the proton
e^- is the eletcron
\bar{
u}_e is the anti-neutrino

Gamma decay

Every rdaioactive decay relesaes gamma rays. It may take place after a particle is rleeased, or by istelf just to make the nucleus more stable.
