Radium and polonium are primarily alpha emitters (an alpha particle is essentially the nucleus of a HELIUM atom, without electrons), as the previous poster noted. But they also emit gamma radiations, and many of the isotopes are beta emitters. There are even a few cases where they emit positrons (for example, Polonium 186).

Alpha particles and beta particles.
Alpha is a helium nucleus (2 protons, 2 neutrons)
Beta particles are electrons.
Some radioactive elements fission into two lighter elements (other than helium and the element with 2 fewer protons...)

As I remember the radiation is alpha, beta or gamma rays. They are harmful to human body because their wavelengths are even shorter than UV light so are more powerful and can cause more damage.

yes, alpha and beta particles like the other guy said. alpha particles are the most dangerous, but they can't penetrate your body tissue. the only way they would affect you is if you ingested it.

got here across by way of Marie Sk?odowska-Curie and her husband Pierre Curie in 1898 seek on youtube periodicvideos they are exciting video clips with reference to the periodic table and each and each different element, steel, compound of the table

helium nucleI or very fast electrons; very often gamma photons.
