Title: Monitoring for radon in water

Abstract

This article focuses on radionuclides elements of interest to utilities and consumers alike. Each of these groups may be interested in a low-cost radiation detector that can be connected to a laptop or desktop computer through either the serial or the parallel port. A complete set of software comes with the detector, and a detailed manual describes operation of the program and discusses the various forms of common radiation sources in a home. Computer programs can run in the foreground and display a scrolling bar chart or in the background while the incoming data are logged, so the user can continue to work on the computer. Data are automatically stored on a disk file. Data collection times can be set for minutes, hours, days, or weeks, thus allowing long-term trends to be identified. The detector can be connected to the computer by a modular telephone cable and can be placed as far away as several hundred feet. Utilities that use surface water supplies are unlikely to detect any radon. Only those plants that use groundwater supplies from areas where radioactive materials are in the ground will have some radon in the water.

  • The first data of the NEMO 3 neutrinoless double beta decay experiment have shown that the radon can be a non negligible component of the background. In order to reduce the radon level in the gas mixture, it has been necessary first to cover the NEMO 3 detector with an airtight tent and then to install a radon-free air factory. With the use of sensitive radon detectors, the level of radon at the exit of the factory and inside the tent is continuously controlled. These radon levels are discussed within the NEMO 3 context.
  • EPA has provided guidelines to homeowners for monitoring and mitigating radon in the home. The effectiveness of these guidelines is dependent, in part, on the accuracy and precision of monitoring methods. This paper proposes a model for radon monitoring accuracy and precision based upon a review of the monitoring literature. The model is then used to quantify the extent of potential misclassification of homes by radon level from the application of EPA guidelines. Short-term monitoring performed in the basement during winter produced conservative (higher than actual) radon estimates, on average. For homes with annual concentrations of 4 pCl/L, approximately 30more » percent will still have short-term results under 4 pCl/L. Underestimation of radon levels is cut by 50 percent or more by the use of monitors on first floor and basement (confirmatory monitoring) as opposed to monitoring the basement alone (screening monitoring). However, following the screening/confirmatory monitoring sequence suggested by EPA increase underestimation at radon levels under 8 pCl/L. The model was found to be sensitive to a number of the assumptions made, and specific follow-up studies are suggested.« less
  • Research report:Studies were conducted to determine the significance of radon in domestic water supplies as a contributor to radon in indoor air. Air and water samples collected from residences in Halifax County, Nova Scotia, were analyzed. The concentration of radon in tap water supplies varied from 47 nCi/l to 370 nCi/l. Indoor air concentrations were from 0.5 pCi/l to 19.1 pCi/l for radon and 0.001-0.025 pCi/l for radon daughters. It is believed that the radon diffuses through aquifers used for the community's water supply, then escapes to interior atmospheres. (8 references, 4 tables)
