The aim.of this study is to com.are the absorbed doses of critical organs of 131I using the m.RD （m.dical Internal Radiation Dose） with the corresponding predictions m.de by GEANT4 sim.lations. S- values （m.an absorbed dose rate per unit activity） and energy deposition per decay for critical organs of 131I for various ages, using standard cylindrical phantom.com.rising water and ICRP soft-tissue m.terial, have also been estim.ted. In this study the effect of volum. reduction of thyroid, during radiation therapy, on the calculation of absorbed dose is also being estim.ted using GEANT4. Photon specific energy deposition in the other organs of the neck, due to 131I decay in the thyroid organ, has also been estim.ted. The m.xim.m.relative difference of m.RD with the GEANT4 sim.lated results is 5.64% for an adult＇s critical organs of 131I. Excellent agreem.nt was found between the results of water and ICRP soft tissue using the cylindrical m.del. S-values are tabulated for critical organs of 131I, using 1, 5, 10, 15 and 18 years （adults） individuals. S-values for a cylindrical thyroid of different sizes, having 3.07% relative differences of GEANT4 with Siegel ＆ Stabin results. Com.arison of the experim.ntally m.asured values at 0.5 and 1 m.away from.neck of the ionization cham.er with GEANT4 based m.nte Carlo sim.lations results show good agreem.nt. This study shows that GEANT4 code is an im.ortant tool for the internal dosim.try calculations.

The clinical success of dental im.lants can be im.roved by achieving optim.m.im.lant properties, such as their biom.chanical and surface characteristics. Nano-structured coatings can play an im.ortant role in im.roving the im.lant surface. The purpose of the present study was to determ.ne the m.st appropriate conditions for electrophoretic deposition （EPD） of nano-zirconia coatings on Ti-6A1-7Nb substrates and to evaluate the structural and biom.chanical characteristics of these deposited coatings on the dental im.lants. EPD was used with different applied voltages and tim. periods to obtain a uniform.layer of nano-zirconia on Ti-6A1-7Nb sam.les. The coated sam.les were weighed and the thickness of the product layer was m.asured. Surface analysis was perform.d by using optical m.croscopical exam.nation, scanning electron m.croscope and X-ray diffraction phase analysis. For in vivo exam.nation, 48 screw-designed im.lants （24 uncoated and 24 nano-zirconia coated） were im.lanted in both tibiae of 12 white New Zealand rabbits and evaluated biom.chanically after 4- and 12-week healing intervals. Results revealed that the use of different conditions for EPD affected the final coating film.properties. Increasing the applied voltage and coating tim. period increased the deposited nano-zirconia film.thickness and weight. By selecting the appropriate coating conditions, and analyzing scanning electron m.croscopical exam.nation and XRD patterns, this technique could produce a thin and continuous nano-zirconia layer with a uniform.thickness of the Ti-6A1-7Nb sam.les. m.chanically, the nano-zirconia-coated im.lants showed a highly statistically significant difference in rem.val torque values, while histologically these coated im.lants enhanced and prom.ted osseointegration after 4 and 12 weeks of healing, com.ared with the uncoated ones. In conclusion, EPD is an effective technique for providing a high quality nano-zirconia coating film.on dental im.lant surfaces. m.reover, the
