Progress on Digital Dosimeter.
Abstract
Recent work on the source of errors in D-RAMS suggests that they might become the basis for a practical digital dosimeter. We carried out a series of experiments to determine if commercially available D-RAMs can function as alpha counters in conventional digital circuits. We exposed a 64K D-RAM to a weak alpha source while operating it as part of a minicomputer memory. Comparison of the errors produced with the counts produced by a good surface barrier detector showed that about 15% of the alpha particles incident on the chip produced bit flips. Proper programming should double this response. a l6K D-RAM, operated at reduced V sub DD gave a somewhat lower response rate to alpha radiation. The test set-ups are described and some quantitative data are presented.
