Gamma rays .It can penetrate several cm of lead.
Nuclear radiation is radiation that is emitted by atomic nuclei in various nuclear processes ( fusion...). There are three types of nuclear radiation:- 1)Alpha----> the least penetrating of all, it can be stopped by a sheet of paper. 2)Beta----> more penertrating than alpha, less penetrating than gamma, can be stopped by an aluminum sheet. 3) Gamma-----> most penetrating, can be stopped by meters of concrete.
Gamma radiation
Gamma rays. They need layers of concrete and lead. They are also still not completely blocked.
Gamma ray, by far. Alfa can be blocked by as little as a piece of notebook paper, buy Gamma (from sources such as a reactor core) will pass through 6 feet for stailsteel-lined concrete and can give a leathal dose in as little as 20 minutes.
Any element that needs to emit it in order to stabilise. And they are not the nuclei of the element, they are made up of two protons and two neutrons, and it is also the most ionising radiation as well.
Gamma rays are by far the most penetrating of the three types of radiation.

The gamma radiation is extremely penetrant.

The Least penetrating form of radiation is Alpha as it only travels 10cm in air and is stopped by paper. Alpha is also the most ionising, Beta is less ionising still and Gamma is the least ionising as photons carry no charge so they have less effect.
Of all the three types of radiation (alpha, beta and gamma), Gamma rays are the most penetrating, being able to travel through a few meters of lead.
Nuclear weapons emit nuclear radiation, with gamma radiation being the most common and dangerous.
An alpha particle
Gamma ray, by far. Alfa can be blocked by as little as a piece of notebook paper, buy Gamma (from sources such as a reactor core) will pass through 6 feet for stailsteel-lined concrete and can give a leathal dose in as little as 20 minutes.
Gamma waves :D
The most dangerous type of radiation is Nuclear radiation which is the one that should be most worried about.
