WebThe curie Unit. The curie \(\left( \text{Ci} \right)\) is one measure of the rate of decay (named after Pierre and Marie Curie). One curie is equivalent to \(3.7 \times 10^{10}\) disintegrations per second. Since this is obviously a large and unwieldy number, radiation is often expressed in millicuries or microcuries (still very large numbers). WebMar 8, 2024 · The discoveries opened the door to understanding the structure of the atom, to radiation therapy for cancer, and to the use of nuclear energy.

WebThe rate for radioactive decay is: decay rate = λN with λ = the decay constant for the particular radioisotope. The decay constant, λ, which is the same as a rate constant discussed in the kinetics chapter. It is possible to express the decay constant in terms of the half-life, t1/2: λ = ln 2 t 1 / 2 = 0.693 t 1 / 2 or t 1 / 2 = ln 2 λ = 0 ...
