The purpose of the Harrisburg Area Geological Society (HAGS) is to stimulate geologic thought, advance and disseminate geologic knowledge, and provide fellowship amongst area individuals interested in earth sciences. Monthly meetings (at GTS Technologies at 441 Friendship Road in Harrisburg) present a realm of geologic topics, ranging from tectonics, coal, carbonate groundwater geochemistry, Martian geomorphology, engineering geophysics, nuclear waste repositories, and ore mineralogy. Field trips allowed members to visit geologic sites within and beyond Pennsylvania. All events are open to the public and free unless otherwise stated.
Up coming events :10-15-15 HAGS AEC mtg Allard Smith Lehigh Valley Radon
A Geologic “Perfect Storm” of Very High Radon in the Center Valley/Coopersburg area of Lehigh County, PA
Presented by: David Allard, PA DEP Bureau of Radiation Protection
Robert Smith, retired – PA Geological Survey
Abstract: In September 2014, a radon mitigation contractor informed DEP of high radon readings located in a newer housing development in an area of Lehigh County just south of the Reading Prong. Subsequent testing revealed readings up to 3700 pCi/L – a new state (and perhaps US) record. [The EPA recommends mitigation for readings >4 pCi/L.]
This presentation will generally cover radon in PA, as well as detail the outreach, testing efforts and findings for this residential area. It will also include a summary of the area’s relationship to the Reading Prong, and mineralogy, geochemistry, & radionuclide distribution in the soil profile, as well as relationships to out-of-state uranium occurrences.
Speaker Bios: Mr. Allard is the Bureau Director of PA DEP’s Bureau of Radiation Protection and the Governor’s official liason to the US Nuclear Regulatory Commission. He has worked as a consultant to the US Department of Energy, and has been involved in various aspects of governmental, industrial, reactor, medical and academic radiation protection for over 35 years.
Mr. Smith is retired from the PA Geological Survey. He currently assists the Bureau of Radiation Protection with radon and radium.
