1 Overhoff Technology Corporation New Developments in Tritium Monitors 1September 2012 HPIC

2 Overhoff Technolgy Our core business: Design and manufacturing of Tritium in Air monitors with ionization chamber detectors Portable Fixed 2September 2012 HPIC

3 Overhoff Technolgy Also: Low Level Tritium in Air Gas Proportional Detectors Passive Samplers (Bubblers) 3September 2012 HPIC

4 Overhoff Technolgy Additional Areas of Interest: Tritium in Water Radon Environmental Gamma Data Acquisition 4September 2012 HPIC

5 Focus of Discussion New Developments in Overhoff Tritium monitors Portable 400AC, 200SS, 2x200-LD, TriCair Fixed 421-HTO; 321BWC, 593, Triathalon 5September 2012 HPIC

6 Portable Model 400AC MDA of about 2 Ci/m 3 Immune to radon Dual channel Electrometer Quad chamber for total Gamma compensation Communication to PC via RS-232; Automatic Gamma Calibration Diagnostics; battery life, power supplies Rechargeable NiMH Batteries Constant flow; 2 LPM (5 volume changes/min) 6September 2012 HPIC

7 Portable Model 200SS Based on the Model 200SB Non-Gamma compensated, uses both chambers for tritium measurement Successor to the Model 394 and AN/PDR cc volume; MDA of 2-3 Ci/m 3 Radon suppression Fast response, 10 seconds to 90% of final reading Low cost 7September 2012 HPIC

8 Portable Model 2x200-LD can be configured as a sniffer to provide real-time indication of the T 2 and T 2 O concentrations which allow the user to quickly identify the source of leakage of tritium from containers. 8September 2012 HPIC

9 Portable Model 2x200-LD Dual channel electrometer T 2 and T 2 O, are selected with a front panel toggle switch Measurement appears on a single digital display. 9September 2012 HPIC

10 10 Model 2x200-LD Portable

11 TriCair Convertible hose connections and traps to measure Tritium or C14 Dual channel electrometer T 2 and C14 are selected with a front panel toggle switch Measurement appears on one display. 11September 2012 HPIC

12 Fixed Monitor Model 421-HTO Nuclear Power Plant Monitor (Heavy Water) High Sensitivity Monitor in the presence of high concentrations of Noble Gases Uses Nafion Dryer, only HTO passes through 12September 2012 HPIC

13 Fixed Monitor Model 321BWC Cart mounted system Is semi-portable Dual chamber gamma compensated 13September 2012 HPIC 1 thick lead shielding for additional gamma compensation

14 Fixed Monitor Model 593 Revamped in 2012 Gas proportional detectors, MDA is 1 kBq/m 3 Measures T 2 and T 2 O, Oxidizer included Noble gas compensation Updated preamplifier Single Board Computer LCD touch screen 14September 2012 HPIC

15 Fixed Monitor Triathalon Family of monitors with multiple configurations for measurement of: Tritium, C14, and Noble Gases 15September 2012 HPIC
