Daughters of Radon - following the Natural Trap thread
The monitoring in Carlsbad started around 1975 or 1976. The discovery of high
levels of radon in Carlsbad Caverns caught all the federal cave management
folks off guard. The "Daughters of Radon" concern resulted in the first ever
Cave Management Symposium in Albuquerque (October 1975). This was arranged by
the Cave Research Foundation and the National Park Service to provide federal
managers - Park Service, BLM, and Forest Service with guidance. For the first
time on a national level federal resource managers became aware that caves
really needed managing, and that cavers were a significant source for useful
information.
The initial concern was for the federal employees who spent the majority of
their time underground.
This meeting happened to coincide with the first real Balloon Fiesta in
Albuquerque. Sandy and I drove up from Alpine, Texas. Our kids were both small
and were tremulously impressed with the "flying dragons" roaring fire in the
sky over our heads. So were most of the symposium attendees. I remember Pete
and Karen Lindsley, Will White, Jack Hess, and all the CRF leadership present.

When I worked there in 1970-71, I
don't recall that any radon monitoring had yet been started. During the
winter, a draft of cold outside air falls into the lower part of the
entrance, moves down along the floor of the Main Corridor and into the
lower part of the Big Room, then warms and recirculates back outside along
the ceiling. I would expect radon levels to be very low along the tour
route while that cold-trap circulation is going on. Did the people doing
the monitoring say how significant were the levels they found?
