	-There are several charcoal-liquid scintillation radon detectors
that have been used. We made over 200,000 measurements with our type.
Materials and labor for making them in large quantities cost about 35
cents. A single technician was making the measurements on about 400 in an
8 hour day. There are other administrative, record keeping, quality
control, and measurement equipment costs. We provided measurements in
quantities of 100 for $3.50 each, providing only a list of measured values
vs vial number.
