depends on the amount of features these particles will get

I guess it would be pretty nice to get them as a feature, even if it doesn't add much.

i want every radioactive element that is appovered and lots of isotopes

i want thorium for reactors and graphite instead of crmc and water

Yes thorium would be very useful it could have reactions like 1 neutron plus 5 pixels of thorium equals two neutrons and one proton and electron
