The gamma particle has the deepest penetration.
A beta particle is an electron or a positron, with a charge of -1 or +1, and a mass of about 1/1836 of a proton. An alpha particle, on the other hand is a helium nucleus, with a charge of +2, and a mass of two protons and two neutrons. The beta particle has more penetration ability than the alpha particle, but the alpha particle is more biologically dangerous when in close proximity to sensitive tissue, such as when inhaled into the lungs.

An alpha particle
When a radioactive nucleus emits an alpha particle, it decreases by two protons and two neutrons. This results in a new nucleus with a lower atomic number by 2 and lower mass number by 4. The emitted alpha particle is a helium nucleus (2 protons and 2 neutrons) and carries a positive charge.
Gamma Ray
neutrino, it barely notices matter. However it is not electromagnetic, it is a product of the weak force.

Look for the metal detector with the most discoveries and deepest penetration.

This is a alpha particle.
An alpha particle itself is not radioactive, but it is the result of a type of radioactive decay called (obviously) alpha decay. The alpha particle is actually a helium-4 nucleus, and it will eventually pick up a pair of electrons and become an atom of that inert or noble gas.
Thorium is a radioactive metal.
