Experimental study of X-ray dose reduction factor when using various size bismuth and lead particles

Low-energy X-rays are widely used during clinical examinations, therefore we need to reduce exposure dose medical staff by using radiation shielding products. Current X-ray materials fabricated embedding high-atomic-number metal particles into a base material. It is valuable derive knowledge concerning and ability from actual experimentation. This necessary because it unrealistic mimic many in the Monte-Carlo simulation. Understanding effect of particle size on reduction factor important, but at this time systematic clarification has not been achieved. In study, aim investigate ability. 28 investigational products were prepared clay. Lead, bismuth oxide having diameters between 1.8 ?m 211.3 used. The effective mass thicknesses related metals (lead or bismuth) set 2,400 g/m2, 1,200 g/m2 600 resulting maximum factors 94.5%, 84.8% 68.0%, respectively. these measured "International Standard Testing Geometry" with tube voltage 70 kV. As result, found that high can be obtained when 40 less. Furthermore, decreased embedded various such as polymer sheets, loss was 2.4% Our findings provide insight development novel guarantee reliability previous studies simulations.
