COMPARATIVE STUDY ON THE SKIN DOSE MEASUREMENT WITH NANO DOT DOSIMETER WITH MACHINE RADIATION WHILE CARDIAC CATHETERIZATION IN CHILDREN

Objectives: Skin dose radiation direct measurement in the children with the help of optical stimulation of the luminescence technology through Nano Dot.

Materials and Methods

The Nano Dot which are (1cm x 1cm x flat plastic cassette) were applied to the skin of the patients with the help of an adhesive tape in the course of cardiac catheterization and skin doses radiation were observed in the time of 24 hours, values of Nano Dot were compared with the available cumulative AK and display and estimation was carried out on a fluoroscopy monitor.

Results: In the total sample of 12 patients the range of the age was four months to eighteen years with a median of 1.1 years. Weight was in the range of 5.3 – 86 kilograms with a Nano Dot documented value of 2.58 – 424.8 mGy, range of the cumulative AK was 16.2 – 571.2 mGy. There was a correlation in the AK and Nano Dot values respectively 0.94 and 0.88. The estimation was carried out through International Electro Technical Commission standards.

Conclusions: OSL application through Nano Dot gave a substitute for direct measurement of children fluoroscopic skin dose in cardiac catheterization. Research outcomes reflect that children actual skin-dose was 1/3 less than AK estimations in the adult sample collection.
