There are various uses for radioisotope devices, also in metrology, broadly conceived. Most often, absorption systems are used. Such systems, though familiar and used for many years, lacked theoretical and methodical descriptions. The monograph aims at filling this gap. The work presents the results of the studies on the absorption system with the use of betaradiation sources, which are often used in measurements of two-phase gas-solid flows. The influence of the radiation beam collimation on the radiation attenuation coefficient as well as the measurement error related to changing location of the absorbent in the measurement have been measured, the interaction of the beta-particle beam with the homogeneous and heterogeneous absorbents and the optimum parameters of such systems have been provided. The model of the radiometric system has been described and the results of the experimental tests of this model have been presented. An original method for calculating the coefficients of radiation attenuation in dispersed absorbents as well as the results of the experiments have been given. The monograph is addressed to both metrology experts and practising constructors who deal with the application of ionising radiation.
