| Summary: | The manuscript clarifies the issues concerning the effective miniaturization
of readout of the plastic scintillators while maintaining their high
detection efficiency and sensitivity. Values obtained from the measurements
of the chosen gamma emitters (60Co, 137Cs, 241Am), at various distances,
were used to compare the detection efficiencies. The organic plastic
scintillators, with the ternary system of different shapes and volumes,
were chosen for the measurement. The detection parameters for the examined
1" PMT, with variable photocathode geometry, were experimentally found and
compared to the normally used 2" PMT, with the circular type of
photocathode. The primary aim of this work was to verify whether, in the
case of mobile applications, such as UAV, it is possible to replace the
currently bulky and quite heavy electronics with a miniature version and
simultaneously preserve their detection parameters. |
