  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..
