Case Two – The Results

Manor Hall

Manor Hall

The instruments showed high levels of gamma radiation in the music room, “morning room”, small parlor, billiard room, and library on ground level but lower readings in the dinning room and “great hall”, on ground level. Twelve of the twenty bedrooms on the second story; and many of the storage rooms on the third and fourth stories of the house had rates on the Geiger counter that were 6-8 times background.

The six houses that had reported Radon values above the EPA’s standard exhibited counts on the Geiger counter that were well above expected background; however, the other fourteen exhibited counts in the range of the rate expected for background. The Geiger counter clicked at the expected background rate when the team was walking outside from house to house.
