Sweden to examine health risks of burning biomass -Cs-137 Pathways
A brief story which just ran on the Reuters' wire may be of interest to some.

SWEDEN: December 6, 2000
STOCKHOLM - Sweden's National Energy Administration said on Tuesday it was
investing 30 million crowns ($3 million) in a project to examine the health
risks from burning biomass..........>>

COMMENT ON THIS STUDY:
Earlier studies of biomass in Sweden by the Swedish Radiation Protection
Institute have shown elevated levels of Cs-137 in the forest ecosystem, and
this present study will likely be considering the airborne emissions of
Cs-137, and the retention of Cs-137 in ash from biomass burning plants
[Cs-137 from general weapon's fallout and Chernobyl] and Sr-90 from
generalized fallout from open air nuclear weapon's testing. Ash from wood
burning power plants is often used as a fertilizer in farming.
For example related to power related biomass woodash use in Vermont in
agriculture, as of a few years ago 3,000 cubic yards of woodash generated
each year from a modest 50 MW[e] wood burning power plant in Burlington, was
being mixed with manure and spread on fields maintained by "organic" food
coops in the Northeast Kingdom of Vermont to grow organic crops avoiding the
use of regular "chemical" fertilizers. This organic produce from fields
being enriched in fallout Cs-137 [and Sr-90] was being sold widely to organic
food coops like Bread and Circus who have taken a very anti-food irradiation
position being opposed to any "irradiated" food. Interestingly, these organic
coops do not seem concerned about using woodash on their fields thereby
enriching the soil in fallout Cs-137 and Sr-90.
Woodash from northern Vermont was found to contain about 15,000 pCi of Cs-137
per kg of ash in a study I conducted of fallout in woodash in 1990, which was
presented to an annual meeting of the HPS . ["Nationwide Survey of Cs-137 in
Wood Ash --Or Woodburner's and Organic Farmers, Is it Time to Kiss Your Ash
Goodbye?, Washington, DC, HPS 1991 Annual Meeting, Washington, DC]
