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 liberation of carbon dioxide which indicates destroying of chlorophyll but the absorption at 400 – 210
nm still exist which reflects the high stability of the group magnesium-four nitrogen atoms (tetrapyrrole) its energy about
3500 kJ mol-1. The resulted carbon dioxide carries by hemoglobin to expel via lungs similar to that produces by biological
activity of the body.Calculation showed that the dosage of two hours radiation in which color of the solution disappeared
(Compton effect) was 5.6 killogray (1 gray = 1 Joule per 1 kg sample) absorbed by chlorophyll before color disappear is
enough to kills 1120 people weight 75 kg each within 14 days when the whole bodies exposure at one time.The samples
glass containers and their white plastic covers of the radiated samples for 4 and 24 hours changed their color to violet may
be due to the rearrangement of their physical structures. Others interesting points will appear in the full article.Capsules
used as carrier for the chlorophyll to take it by children.
