Light/Silver Unbrand Durable Ion Chamber Smoke Carbon Monoxide Wifi Smart Sensor Alarm Fire Detector Size 1
Product Description
Description: 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). Specifications: 1) Ionization source characteristics and radiation safety performance: 2) Ionization source activity: 0.5uCi ( 18KBq ) 0.8uCi10% ( 30KBq10% ) 3) Ionization source a spectroscopy: peak: 4.5MeV 10%, FWHM<0.7MeV 4) Safety gradingstandards ( GB4075, IS02919 ) C64444 5) Ionization chamber radiation dose rate at 25cm: 0.03mGy/ ( 1mGy value lower than population dose standard ) 6) Ionization chamber specification, parameter: 7) Conditions: outer electrode and the source electrode voltage ( VDDsupply voltage ): 9V 8) Environment temperature: 20 + C: close to atmospheric pressure standard atmospheric pressure, clean 9) Collecting electrode equilibriums potential: 5.3~6.5V 10) Collecting electrode potential with the smoke concentration change 11) Light reduction rate was1% feet: 0.6Volt 12) Light reduction rate was4% feet: 2.2V 13) Insulator leakage current Max0.5Pa 14) Capacitor ( collection of extreme outer electrode + to the source base ): 6.0pF Material: Metal Color: Silver Size: 27x15x37mm/0.8"x1.1"x0.5" Package included: 1x Smoke Detectors Sensor
