Carbon Monoxide Detect Fire Alarm Smart Sensor for HomeOffice Hotel School

emits for alphaparticles and weak gammaradiation, for alphaparticles completely blocked by the casing of the sensor, gammaradiation however freely passesthrough the casing but due to very low energy around 60keV quickly absorbed by (maximumrun through 15cm).

Add a nice "hot" piece to your collection which emits for alphaand gammaradiation.

SBM20 tube basedcounter indicates 140 Counts per minutes from this source with gammafilters applied (approximately 80uR/hour or 0.8uSv/hour accordingly).
