This research aimed to compare the method of determining pore size distribution of nine Fine Aggregate Matrix samples using X-ray micro-computed tomography to the method of determining pore size distribution by analyzing a set of linear regressions between the pore volume and the density of the samples. The results showed that the pore distribution obtained through linear regression resembles the pore distribution obtained from X-ray computed microtomography and that the average sample density overestimated the linear regression set model by up to 6.1 % of the pore volume. The observed sampling error was less than 0.59 %, which shows that the number of samples was sufficient to estimate the pore volume of the FAM2. Thus, the hypothesis test result confirmed that the difference cannot be considered significant for a 95 % confidence level.

This study proposes a method for using CR-39 to measure low LET radiation, such as photons and electrons, at high doses in the order of kilogray (kGy). CR-39 detectors were irradiated with bremsstrahlung photons generated from 10 MeV electrons striking a tantalum target, resulting in absorbed doses ranging from 6.5 kGy to 261.4 kGy. FLUKA Monte Carlo simulation was performed to estimate the dose deposition in CR-39 due to bremsstrahlung photons and to estimate the primary and secondary electron fluences incident on CR-39. The simulations revealed that the secondary electrons produced by the interactions of primary electron beam were of two orders less magnitude than that of bremsstrahlung photons. The results showed no significant changes in the absorbance values of different functional group vibrations of unetched CR-39 even they were exposed to high dose up to 261.4 kGy.
