Comparison and Study of the Bulk Etch Rate of the Detector CR-39 using Two Etching Solutions

Abstract : In this research, we studied the effect of two types of etching solutions on the bulk etch rate(VB)of the nuclear track detector CR-39. The first type of solution was prepared from dissolving NaOH in (ethanol+water) by different normalitiesat temperature 55ºC and compared with the second type of the solution prepared from dissolving NaOH in (methanol+water) by different normalities at temperature 55ºC.The method of direct measurement of the thickness of theremoved layer by the chemical etching of the detector was used in finding the bulk etch rate values. It was found the  values of the bulk etch rate by using the etching solution NaOH/methanol+water greater than the values of the bulk etch rate by using the etching solution NaOH/ethanol+water, Their values have ranged between (4.48-10.62)um/hr for NaOH/ethanol+water and ( 15.64-35.51)um/hr for NaOH/methanol+water.
