Beta Radiation has a negative 1 charge
and compared to gamma, its danger isn't that large
It can be stopped by lead or glass
549 millionths of one AMU is their mass
But don't think it's still not dangerous
Because anything with radiation is outrageous
Alpha Radiation's charge is negative 2
and skin or paper will stop it from going through
There are 2 protons and neutrons inside
Though the particle is not very wide
It is a type of radioactive decay
and people come in contact every day
