Radioactive decay

    Is radioactive decay dependant on temperature? what about pressure?

    my initial thinking is yes and no

    Welcome to the PF. Why do you think those are the answers. What sources of information did you check out in order to get to those answers? What physical mechanisms are you thinking are behind any change versus temperature and pressure?

    because pressure has no feed into any reactivity equations I have seen. however temperature increases how fast particles move.. and temperature affects pressure so im confused

    Radioactive decay is a property/phenomenon of the nucleus.

    Temperature and pressure affect the atom, and are related to the translational motion of atoms., or in the case of a compressive stress, pressure relates to a local force applied to a unit area.
