"Bad" types of radiation are the types that hurt you. So there is no really bad types, only bad uses.
See the website here for the different types:

Then decide for yourself what is a good use and a bad use for the different types of radiation.
Alpha and Beta Radiation are types of ionizing radiation. They are both charged particles though Alpha is heavier than the particle Beta.
There are 3 types of radiation used. The first is alpha,beta, and gamma order from weakest to strongest.
beta radiation!
Beta radiation is made from electrons (or positrons for inverse beta radiation). Alpha radiation is a helium nucleus, and gamma radiation is a high energy electromagnetic ray.
A stream of helium nuclei is alpha radiation. Beta radiation is a stream of electrons.
It is the heaviest of the three types.
alpha , beta, gamma

Different types of radiation
Beta particles or radiation is an electron emitted at high speed or energy from some types of unstable elements in a process known as beta-decay. Beta radiation is not healthy for living things. It is usually stopped by a few millimeters of metal, wood, or plastic. Direct exposure to the skin can cause radiation burns.
Radiation is neither good nor bad. All types of radiation can be useful for some purpose, but many can be harmful in overdose conditions.
Alpha, Beta, Gamma and cosmic are all examples of radiation.Types of radiation could be:Ionizing radiationElectromagnetic radiationInfra red radiation
There are only three types of nuclear radiation - Alpha, Beta & Gamma.
