| 520 | |a"A portable radon detector has been successfully developed based on spark discharge technology . This detector was found to have a sensitivity to radon of 0.045 cpm/pCi. Research focused on the development of a low cost, high voltage supply, counting systems, various sensors, and a radon daughter electrostatic collector. Sensors based on conventional technology were constructed, optimised for sensitivity, simplicity of fabrication and stability. Sensors based on thin foil technology failed to function as expected and research was discontinued. Testing was ongoing throughout the project"--Executive summary. |
