A radioactive decay series that begins with 237/93 Np ends with formation of the stable isotope 209/83 Bi. How many alpha particle emissions and how many beta particle emissions are involved in the sequence of radioactive decay?© BrainMass Inc. brainmass.com October 16, 2018, 4:15 pm ad1c9bdddf
The nuclear equation is:
237/93 Np --> 209/83Bi + x * 4/2 He + y * 0/-1 e
where 4/2 He is an alpha particle, ...
The solution provides clear, concise steps to finding the number of alpha and beta emissions of a radioactive decay series.
Half-Life of a Mixture
Would you help me with the following problem?
An assay of an equilibrium ore mixture shows an atomic ratio for U-235 / Pa-231 of 3.04 X 10 ^6 . Calculate the half-life of U-235 from the assay data and the known half-life of Pa-231 (3.28 x 10^4 y). Ignore the Th(231) decay product.View Full Posting Details
