The law of radioactive decay
SpletNow although charge is conserved via emitted beta particles, locally within a radioactive substance, could this not be thought of as a "quark discharge" throughout the material, as in the down quarks are being "discharged" via beta decay until the "neutral state" of being an up quark is achieved resulting in a proton. SpletIt follows that: d m d t = k m (2) where k is a negative constant. In other words, radioactive substances decay at a rate proportional to the remaining mass. This means that we can use to show that the mass decays exponentially: m ( t) = m ( 0) e k t (This equation I understand and accept, the above two confuses me)
