Interpretation: The definition of Geiger counter, scintillation counter and their working is to be stated. Radiotracers are to be defined. The reason for
Concept introduction: Geiger Muller tube detects and measures all type of radiations. The radiation entering the tube ionizes the gas present there. Not all the emitted radiations enter the Geiger Muller tube. Radiotracers are used in the medical sciences to learn about metabolic pathways.
To determine: The definition of Geiger counter, scintillation counter and radiotracers. The reason for
