Interpretation:
Manner in that radioactivity can be used to locate leak in under ground pipe has to be determined.
Concept Introduction:
Radioactivity is a nuclear process. It is defined as the spontaneous disintegration of a nucleus which is done by the emission of radiation. The elements which show this property is said to be radioactive elements. Radioactive elements undergo decay by emission of alpha particles and beta particles.
Alpha radiation is the flow of positively charged helium ions that contain two neutrons and two protons and beta radiation is the flow of electrons. Gamma-ray is a stream of
