Skyddsproblematik i Radioacktiva Belaeggningsomraden. Kontaminering och Sjaelvsanering av Bandvan 206. Kortversion. (Contamination and Decontamination of All Terrain Carrier BV 206 When Driven in Radioactive Areas. Short Version.)

摘要

There is reason to ask whether it is beneficial to decontaminate vehicles, in view of the great effort applied. If the level of contamination is low before the decontamination process, then the cost may not be motivated, even if the decontamination is shown to be effective in relative terms. The report, which is a short version of a final report with estimated release during the first quarter of the year 2000, describes a trial made at the National NBC Defense School in Umea and the calculations of contamination levels on vehicles and the resulting doses to the personnel. The radioactive Sodium 24 was dispersed along a 500 meters long loop of a gravel road and after that a BV 206 was driven along the loop repeatedly. Samples were taken in 34 places on the vehicle after 1, 2, 3 and 6 kilometers and the amount of Sodium 24 in the samples were analyzed. From the test results contamination and decontamination constants were calculated. The trial was made during winter conditions. A comparison with results from earlier trials is made.
