Staff and Instructors

Jan Carrington
Jan Carrington is the SRRTC program manager for the Southern Regional Radon Training Center (SRRTC) based in the Business and Engineering Continuing Education office at Auburn University, AL. Ms. Carrington has coordinated all phases of radon training through organizing programs and examinations throughout the 13 southeastern states since 1990. Ms. Carrington maintains the SRRTC 800 Radon hotline and also assists with other Business and Engineering Continuing Education programs as a program developer.

Jack Hughes
Jack Hughes entered the radon industry in 1989 after fifteen years as a building contractor. Since 1998 Mr. Hughes has been the lead instructor for the Southern Regional Radon Training Center (SRRTC). In addition to presentation of standard measurement and mitigation courses, his duties include development and presentation of specialized courses for various audiences, and design and implementation of investigative projects. Since starting with the SRRTC he has developed a mitigation course for school maintenance personnel, enabling cost-effective in-house solutions to school radon problems. As chief investigator, he has overseen the USEPA/Tennessee/SRRTC investigation into karst geology and its influence on radon behavior and the associated problems of measurement and mitigation. This effort now includes additional investigations into the karst/radon phenomena in several states.

Robby Cardwell
Robby Cardwell is an instructor and technical assistant for the Southern Regional Radon Training Center (SRRTC). He has a broad background in mechanical, civil and environmental engineering and a graduate from the University of Tennessee. He has 15 years experience in the home construction industry. In addition to providing the "hands-on" environmental services, he also performs educational workshops for the above referenced subjects to schools, homeowners and the real estate industry. He provides technical and educational assistance to the SRRTC through various training programs, such as combined measurement and mitigation courses, real estate seminars and schools measurement and mitigation.

Bradley Turk
Bradley Turk is a research consultant and president of Environmental Building Sciences in Las Vegas, NM.  His work includes contracts with private businesses, state governments, universities and the U.S. EPA to investigate indoor air quality, radon and energy efficiency in residences, schools and offices and to develop courses on these topics.  Mr. Turk is a trainer for the regional radon training centers consortium.

Mr. Turk has a BA in Physics from Colorado College and experience investigating the indoor environment that stretches back over 20 years. He has served as a staff scientist at the University of California Lawrence Berkeley National Laboratory where he directed field research on indoor air quality, ventilation and radon in residences schools and commercial buildings.

Studies have included extensive pollutant monitoring and determination of ventilation rates using tracer gases and blower door leakage areas. He performed some of the founding research in radon measurement, diagnostics and mitigation in high radon house, beginning in 1985. He is an author and reviewer of numerous publications on IAQ and makes presentations at scientific and technical meetings and conferences.

Harry Grafton
Harry Grafton has been involved with a variety of indoor environmental issues for more than a decade. He has been an instructor for EPA and has taught courses such as Introduction to Indoor Air Quality, Building Air Quality, Radon Measurement Operators Course, and Radon Training for Mitigators across the country. His approach to indoor air quality is to consider the building and the occupants as a system, rather than to consider each pollutant individually. Mr. Grafton is a trainer for the regional radon training center consortium.
