measurements of Radiation Depth Dose curves of radiotherapy device rta
Biomedical Engineering, 1997Co-Authors: V N Vasilev, A A KokontsevAbstract:Depth Doses for Radiation of superficial x-ray therapy unit RTA were measured in tissue-equivalent medium using an ionizing chamber. The measurements were made for high voltage (30-80 kV), treatment cone 8 cm in diameter and source-surface distance 30 cm. Necessary correction of the results was performed and the estimated error on a half-Dose level was equal to 5.3% in 95% confidence interval. The results were in good agreement with Markus and Kasten's data but in disagreement with the data from current guide of practice on superficial x-ray therapy and the difference in half-Dose level was up to two times.

evaluation of the Radiation Depth Dose curves of an rta x ray apparatus
Biomedical Engineering, 1997Co-Authors: V N Vasilev, A A KokontsevAbstract:The values of Depth Doses in a tissue-equivalent medium were measured with an RTA X-ray apparatus under standard irRadiation settings (30–80 kV; tube diameter, 8 cm; and path length, 30 cm). The measuring error for the HDL values was estimated as 5.3% with the confidence limit of 95%.

a continuous osl scanning method for analysis of Radiation Depth Dose profiles in bricks
International LUMDRTR'94 conference, 1994Co-Authors: L Botterjensen, Hogne Jungner, N R J PooltonAbstract:Abstract This article describes the development of a method for directly measuring Radiation Depth-Dose profiles from brick, tile and porcelain cores, without the need for sample separation techniques. For the brick cores, examples are shown of the profiles generated by artificial irRadiation using the different photon energies from 137 Cs and 60 Co gamma sources; comparison is drawn with both the theoretical calculations derived from Monte Carlo simulations, as well as experimental measurements made using more conventional optically stimulated luminescence methods of analysis.
