Using The chlorophyll as gamma absorber
Author(s): Jaleel Kareem Ahmed*
Chlorophyll extracted from celery using 50% v/v water – methyl alcohol as a solvent. By this method the concentration
of chlorophyll was 22.6% with yellowish-green color. This solution showed strongly absorption at 400 – 210 nand maximum
was at the end of ultra-violet region. This absorption appeared in water, methyl alcohol, and acetone, but strongest
absorption was in water. No emission spectra was detected in the ultra-violet and visible regions which means that chlorophyll
absorbs radiation and dissipate it as a heat.Several samples of the above solution was radiated by gamma ray from
cesium-137 with energy of 0.7 Mev for different intervals (0.5, 1, 2, 4, 24 hours). The color of the solution disappeared
after two hours radiation while the pH decreases from 6.38 for unradiated to radiated celery solution 4.17 after 24 hours
radiation with liberatio.. View More»
