HIV represents a significant public health challenge, contributing to increased mortality and morbidity in developing countries, particularly Sub-Saharan Africa. While HIV testing is crucial for early treatment and prevention, the uptake of the HIV testing among the adolescent and young adults in Botswana remains low. This study aims to predict barriers to HIV testing uptake among adolescents and young adults.
In this work, weset out to find out whether using torso shielding actually helps reduce scatter radiation to the chest during head CT scans in adults.Fifty adult women scheduled for routine head CT scans took part in the study. Thermoluminescent dosimeters (TLDs) were stuck on the central area of both breastsanteriorly. The left breast was shielded with a 0.35-mm lead apron, while the right breast went unshielded as a control. Standard head CT protocols was followed. After the scans, absorbed dose was quantified. Both breasts were evaluated statistically using paired-sample t-tests. Effective dose was estimated using standard ICRP-103 tissue weighting factors
