Re: Naturally-occurring Tritium

[Bernard L Cohen <blc+@pitt.edu>]

	According to the 1982 UNSCEAR Report, before nuclear explosions
the concentration in surface waters was 200-900 Bq/m3 for continental
waters and 100 Bq/m3 for ocean waters. There have been very large
increases due to bomb testing, more than a factor of 100, and 4x more in
the Northern hemispher than in the Southern hemisphere.e
