[4] Unfortunately, lead may present an insidious health hazard to pediatric patients because of the lead dust that is readily removed from the surface of lead objects in the Nuclear Medicine and Radiological departments. Although the density of lead dust is high, it may still become airborne, contaminate floors and other nearby work surfaces, and be inadvertently inhaled or ingested. [5] The adverse health effects of lead exposure in children and adults are well documented. [6-10] There are also reports on the need for corrective measures due to corrosion of lead sheets when lead is used for structural shielding. [11] Based on the above mentioned facts, production of environmentally friendly non-toxic lead-free radiation shields which provide less weight compared to conventional lead-based shields remains a challenging issue in radiation protection. [12] The use of lead free shields has been associated with some unexpected problems such as being efficient only at a limited tube-voltage range. [13,14] Efforts have been made
