This paper reports on a prototype skin dose monitor that has been constructed and tested successfully. The monitor uses an ion-implanted silicon detector available commercially. The ion-implanted silicon detector was selected since it has a lower leakage current than the other type of silicon detectors. It operates on both a pulse mode and a current mode, and there is an overlap in the measurable beta dose rate ranges of these two modes. Our prototype device includes an 8-bit A/D converter and an 8-bit microprocessor to display the skin dose directly. The device presently covers more than five orders of magnitude in the measurable beta skin dose rate ranges. The device has been calibrated using an extrapolation chamber and is then used to measure the dose rates produced by several different beta and beta/gamma sources.
