Question
Chapter 9.3, Problem 9.3P
Interpretation Introduction
Interpretation:
An equation for the nuclear reaction of positron emitter of Arsenic-74 should be determined.
Concept Introduction:
When an atom on undergoing radioactive decay release a positron and electron neutrino due to conversion of the proton inside a radionuclide nucleus into a neutron then such type of radioactive decay is said to be positron emission.
