I'm thinking, I know that we have neutrons, but what other radioactive category elements might be fun to have? Gamma radiation would essentially have the same properties as light, except that it'd be chiefly invisible besides its effects on other mass, alpha and beta decay particles might have some sort of use. A fissible element that doesn't fall to the ground like a powder would be interesting.

Also, if there were microwaves or infrared radiation, fires could emit these and heat up nearby objects without immediately touching them.

...Would there be any application for radio waves? :O


I'm sure there's lots of things that might fit into this category of elements, between radioactive and radiation.
