Beta Plus Decay: Beta plus decay, also known as positron emission, occurs when a proton in the nucleus converts into a neutron while emitting a positron.
Radioactive Isotope: A radioactive isotope is an unstable form of an element that undergoes radioactive decay over time.
Neutron Activation Analysis (NAA): Neutron activation analysis is an analytical technique used to determine trace elements by bombarding samples with neutrons and measuring resulting radiation emissions.
