A series of experiments was performed to study the effect of etchant, concentration of etchant, bulk-etching rate and track diameter distribution in Daicel Cellulose Nitrate and Cronar plastic detectors.
Californium-252 (cf-252) was used as a source for Spontaneous Fission Fragments (S.F.F)
The bulk etching behaviour of Daicel cellulose Nitrate depends on the normality, the temperature.
From the measured bulk-etching rates at different temperatures, the activation energy for bulk-etching has been obtained. The activation energy, Q, was found a value of 1.06eV for Daicel Cellulose Nitrate detector.
When Cronar was etched with 6.25N, NaOH and KOH and at 69˚C, the maximum ratio of maximum length to maximum width were 6.15 and 7.07 respectively.
Cronar was etched better with NaOH than with KOH at a given normality.
