RE: British Radioactive Pollution

["Lieskovsky, Miro" <MLieskovsky@nbpower.com>]

RADSAFERS:

I wonder:

1. What method was used to measure the activity of Tc-99 in that
seaweed... ? In ICRP38 no gamma/X-ray is listed for this isotope and the
average beta- energy is 101 keV and IMHO this is not easy.

2. Why there are no other isotopes reported? 

3.Should not there be also another fission products with reasonable
half-life and/or "somehow similar" chemical properties?

Thx.
