Abstract EN

The attenuation measurements of x-ray of voltage range (21kv) for hosted polymer material were done using x-ray unit, in order to extract the effect of adding carboxy methyl cellulose material (CMC) to low density polyethylene on x-ray radiation attenuation .

The linear attenuation coefficient (μl ) was calculated for the voltage range mentioned above , through linear equations of the yield of graphic representation between the logarithmic absorption and the sample thickness X(cm).

The mass attenuation coefficient (μm ) could also be calculated through the graphic relation between the logarithmic absorption and the equivalent thickness of the sample Xm(gm/cm2 ) such that slope of the graphic relation represents linear the attenuation coefficient or mass attenuation coefficient.

The calculated results indicated that the efficiency of prepared material to absorb X-ray and to attenuate it were high.

this efficiency change relatively according to the added ratio and on type of material .this indicate a significant positive result for these adders on the characteristic radiation attenuation of the polymer,1 low density polyethylene.
