Evaluating organ dose and radiation risk of routine CT examinations in Johor, Malaysia

In this study, radiation doses from CT scan procedures and its related risks to the patients from five hospitals in Johor State, Malaysia were analyzed. The survey was conducted in a two-month period encompassing data for 460 patients with the number for each hospital being set at 32, 30 and 30 samp...
