Study of radiation and natural aging of plastic scintillators
An influence of radiation and natural aging on scintillating characteristics of polystyrene scintillators (PS) produced by different technologies is studied. Influence of molecular-mass distribution on PS radiation hardness is also studied. It is shown that with increasing of polydispersion a radi...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | An influence of radiation and natural aging on scintillating characteristics of polystyrene scintillators (PS) produced
by different technologies is studied. Influence of molecular-mass distribution on PS radiation hardness is also
studied. It is shown that with increasing of polydispersion a radiation hardness decreases, which is connected with a
change in a free volume of polymer and ultimately with amount of dissolved oxygen. By results of accelerated tests
on radiation and thermal aging, assessed operation times are presented for PS of different types. Recommendations
are proposed regarding PS selection for different operation conditions. |
