Abstract:
ABSTRACT Track densities and uranium concentrations were calculated for 50 human tissue samples (breast and uterus) back to patients subjected to surgical operation .These samples were collected from the educational laboratories belong to medical Baghdad city. Samples were prepared, pressed into pellet, and inserted between two pieces of CR-39 as sandwich. Neutron induced fission technique has been applied to determine uranium concentrations by irradiating the composition (detector-sample-detector) with fast neutron emanated from (Am214-Be) neutron source, to let fission tracks resulting from nuclear reaction 238U (n, f) registries on CR-39 detectors. Tracks produced in the detector are enlarged, viewed, and counted by optical microscope after etching the detector by two different chemical etching technique; the conventional (water bath) and new (microwaves). For the first time in our research many etching times were be examined to approach the appropriate time for developed the potential tracks in CR-39 detector originate from uranium fissions, which is be ( 8 )mints. The track densities calculated in microwave etching technique were slightly less than the number calculated using microwave, and the same thing applies for uranium concentrations. The mean average uranium concentrations calculated when using water bath technique were (0.062ppm) and (0.060ppm) for uterus and breast respectively. For microwave technique the mean average uranium concentrations were be (0.047ppm) and (0.039ppm) for uterus and breast respectively. Our results will agree with world uranium concentrations values calculated in human tissues. Finally, we would like to mention that the present study is considered to be very important because it affect people s health Keywords: CR-39, uranium concentration, fission fragments, microwave etching, biological samples.
