Here are some examples of the dreaded radioactive gauges that DRMO has been concerned about. Pic 1 is a new gauge with no radiation. Pic 2 is a WWII gauge with .5 milliroentgens/hour (mr/hr). Pic 3 is a M-Series gauge with .5 mr/hr. Pic 4 is a M-series gauge with .6 mr/hr. Pic 5 and 6 of M-Series gauges are the hot ones, they are 10 mr/hr. these readings were taken on an uncalibrated 1960's Victoreen 6B geiger counter. In all cases the identifier is yellowed coatings on the numerals and needle. Much has been assumed about these gauges, but whatever you do, don't open them up and bead blast the gauge face!
