Abstract

We studied about dosimetry according to the X-ray tube voltage, radiation field object thickness and obtained results as follow. 1. Secondary ray involing rate in the penetrated radiation increased proportion to the tube voltage, but its rate is more larger at the small radiation fields. than large fields. 2. Secondary ray involving rate in the penetrated radiation increased at thick object and large exposure fields. But saturated phenomenon appeared at limited field. 3. Secondary involving rate of acryl phantom is more top place than water, paraffin and aluminum phantom.
