[Draining of radioactive waste water from departments working with radioactive material after introduction of the law for radiation protection (author's transl)].

In order to establish the drainage of radioactive waste water 1976 in the Federal Republic of Germany a new law for radiation protection was introduced. In this paper a concept is introduced how to determine specifications for constructing a decay plant using the given data of a department for nuclear medicine. The given boundary conditions were to secure a low concentration of radioactive material in order to establish the drainage of extreme low activities without diluting it.

[Body build and radiation exposure in static roentgen studies (I): A contribution for determining a national reference dose value. Promoted by the Federal Office for Radiation Protection (St.Sch 4163)].

PURPOSE: To contribute data on radiation exposure in static x-ray procedures and to compare them with anthropometric parameters. METHOD: 121 chest x-rays and 100 lumbar spine examinations were carried out and the dose-area product (DAP) measured for each of the projections. Additionally, body height, body weight and the sagittal and transversal diameters of the examined regions were recorded. Dose measurements were statistically evaluated and the following data determined: Frequency distribution, median, 25%- and 75%-percentiles as well as correlations with sex, body weight and diameters. RESULTS: Median DAP was 13 (men: 16; women: 11) resp. 50 (62; 37) cGycm2 with pa resp lateral chest x-ray. Values were closely correlated with body weight (r = 0.704/0.659) and diameter of the chest (r = 0.657/0.579). Median DAP was 175 (239; 126) resp 531 (670; 361) cGycm2 with ap resp lateral lumbar spine examinations. Values were closely correlated with body weight (r = 0.678/0.666) and diameter of the abdomen (r = 0.664/0.658). CONCLUSIONS: DAP of chest x-rays and lumbar spine examinations is strongly influenced by the constitution of the patients. Men are nearly twice as largely exposed to radiation as women.
