Inverse-square law and absorption of gamma or beta rays with the Geiger-Müller counter

Article No: P2524101

The inverse square law of distance is demonstrated with the gamma radiation from a 60-Co preparation, the half-value thickness and absorption coefficient of various materials determined with the narrow beam system and the corresponding mass attenuation coefficient calculated.
