Abstract

The primary objective of this study is to investigate the optical properties of polyvinyl alcohol (PVA) based polymer films, incorporating methylene blue (MB) dye and trichloroacetic acid (TCA), for their potential application in gamma radiation dosimetry. Specifically, this research aims to explore the effects of gamma radiation on the color change characteristics, optical absorption spectra, activation energy, and optical band gap energy of the PVA-MB-TCA polymer films. Additionally, the study seeks to assess the stability of these polymer films under varying doses of gamma radiation, ranging up to 14 kGy. The PVA-MB-TCA polymer films were prepared using a solvent-casting method. The polymer film samples were then exposed to gamma radiation from a 60Co source, with doses up to 14 kGy. The study observed significant color changes in the polymer films, transitioning from blue at 0 kGy to light blue-near transparent at 14 kGy. Spectrophotometric analysis identified three distinct wavelengths of maximum absorption at 360 nm, 440 nm, and 560 nm. As the radiation dose increased, absorption values decreased at 360 nm and 440 nm, while an opposite trend was noted at 560 nm. Furthermore, the activation energy of the polymer films was found to decrease with increasing radiation doses, indicating a reduction in the energy barriers for internal reactions. Similarly, the optical band gap energy also showed a decreasing trend with higher radiation doses across all types of transitions. These results demonstrate that the PVA-MB-TCA polymer films undergo significant optical and structural changes when exposed to gamma radiation, highlighting their potential utility as reliable high-dose radiation dosimeters. The stability of these films under radiation further supports their applicability in various fields requiring precise radiation dose monitoring, such as medical sterilization, food processing, and environmental safety.

Abstract

It is widely stressed that girl-child education is good; and girls could only learn properly if they are fed well. Levels of micronutrients such as antioxidants vitamins A and C could lead to poor brain or nervous system functions. The objective of this work was to evaluate the relationship between Micronutrients deficiencies (poor levels of antioxidants Vitamin A and Vitamin C) and academic performance of selected young girls in Sokoto, Nigeria. This work determined blood levels of vitamin A and C in 250 young girls in Sokoto using standard methods and materials of analytical grade. A semi experimental study involving 40 selected study participants was done. An exploration of academic performance of subjects that are with enough vitamin C and A and their counterparts was done using assessment. This study shows that, the girls with normal levels of antioxidants vitamins A and C scored a mean mark (55.0+ 13.015) more than those with poor levels (35.63+12.63) (p<0.05). This signifies that nutritional concerted interventions are needed. Nutritional education, soil fertilization, bio fortification, and relations could be used for improving public diet in the state.
