RAM-100 multifunction radiometer

 RAM-100 multifunction radiometer RAM-100 portable multifunction nuclear radiation detector is based on rapid emergency response monitoring technology requirements, specifically for nuclear medicine, molecular biology laboratory, transport of nuclear material and other presence αβ γ radiation and surface contamination The terms of design, is a high sensitivity of intelligent portable instrument. It combines surface contamination monitors and γ dose rate meter function of the two instruments, can be used to measure surface contamination caused αβ, it can be used to measure the γ radiation dose rate. Main applications: workplaces, laboratories, hospitals, isotope production plants, countertops and other αβ and γ radiation places radioactive pollution radiation dose rate testing. The main technical indicators: 1. Measuring range: α: 0 ~ 104cps; β: 0 ~ 104cps; γ: 0.01 ~ 100μGy / h. 2. Temperature: Operating -20 ℃ ~ + 50 ℃; storage -20 ℃ ~ + 60 ℃; 3, energy response: 25KeV ~ 3MeV, change is limited to 15%; 4, the inherent error γ dose rate indicated: less than 10 %; angular response: (137Cs) does not exceed 15%. 5, humidity range: 40% ~ 95% RH (without precipitation water); 6, the unit of measurement: cpm / CPS, uSv / h 7, detection efficiency (for 90Sr + 90Y (β)): 54%, the surface sensitivity (for 90Sr + 90Y (β)): 500; 8, flat probe effective diameter: φ50mm; 9, sensitivity (137Cs): 342cpm / (mSv / h); 10, background reading: 20cpm; 11, measurement error: 10%; 12.
