John:

>From one of the papers on Kerala - the 'prototype' HBRA - that I provided to you (Chougaonkar M P, Eappen K P, Ramachandran T V, Shetty P G, Mayy Y S, Sadasivan S, Raj V V, Profile of doses to the population living in the high background radiation areas in Kerala, India. Journal of Environmental Radioactivity, 71(2004)275-297)

The indoor gamma ray dose measurements were carried out using thermo luminescent dosimeters (TLDs) and the inhalation doses due to RADON [a major contributor to equivalent dose, my emphasis R.F.], thoron and their progenies were monitored using solid-state nuclear track detector (SSNTD) based twin-cup dosimeters.

It appears increasingly difficult to determine what in fact you are really interested in.

Kind regards, Rainer

Dr. Cohen,
Do your studies include high background radiation levels?  Did you look at longevity or only cancers?

Again, I am not interested in radon, but with ambient exposures.
