Was to produce a new shield the light that is based on the silicon in consideration of theharmfulness of the lead apron is used during the inspection at the Department of Radiology present study.
The shielding material comprising a variety of compounds, and to provide a basis for the development ofnew shielding material. Silicone mixture was prepared by mixing 07 kinds of silicone compound forhardening compared to the shielding performance evaluation tests. Digital diagnostic X-ray was studied thereliability of the generator over the line X-ray and the line reproducibility evaluation. To yield acompound that is used by the dose value transmission tube voltage is fixed at 110 kVp and the tubecurrent 20 mAs,. 40 mAs, 80 mAs, 100 mAs, the result obtained by 200 mAs to be varied in order tomeasure 10 times. Reproducibility of the X-ray output and the linearity of the measurement results, theresults of diagnostic digital X-ray showed both linear to suit the criteria of the CV value generator. 110kVp fixed, in comparison to the dose according to the mAs value of each element by the atomic weightis lower resulting change in the value of the dose showed a significant difference was highly statisticallysignificant. However, there was no change in dose value corresponding to the atomic mass or less inatomic weight of 14.64. In about 110 kVp fixed, according to the mAs change each element by comparingthe transmittance showed high transmittance of the lower atomic weight. Digital diagnostic X-raygenerator, and the reproducibility of the results of evaluation were as deviating from the allowable rangeof the coefficient of variation not more than 0.05, respectively (CV) are all. Results were also evaluatedthe linear fit to the standard of less than 0.1. 110 kVp fixed, the elements according to the mAs value bythe dose change of NaCl was the highest dose value is the value of the lowest dose of lead was found.
The results showed dose value of the lead other than the barium lowest. Also, in general the lower theatomic weight was higher dose value. 110 kVp fixed, each of the elements by the transmittance due tochanges in mAs was the highest permeability of the low permeability silicon showed the lead. Also, ingeneral the lower the atomic weight was high transmittance.
