Question

Will Alpha and Beta radiation cause genetic mutation?

Answer 1

Or all the radioactive radiation can cause genetic mutation?

Answer 2

All 3 types of nuclear (radioactive) radiation can cause cell mutations (as well as EM radiation). With alpha and beta, they can ionize atoms by collsion. Gamma rays and EM waves (obviously there is an overlap here) can ionize atoms by giving them energy, but it is much 'harder' to do.

A cell mutation is simply when a cell is altered from being normal and doing its job, and this can be a result of atoms in the cell being ionized by radiation. The genetic material in the cell can certainly be damaged, and certainly a large number of people affected by Chernobyl gave birth to babies with deformities and abnormalities.

Alpha radiation is the most ionizing, and if consumed it cannot escape the body and so it will likey kill you as so many cells are damaged. (Look up alexander litvinenko). Hope this helps, feel free to ask anything else.
