Basically, radiation is effecting the ability of natural decomposition processes in the exclusion zone. A study was conducted with natural leaves in panty hose bags within the exclusion zone and outside it. 60% percent of the weight of the bags was still retained in the exclusion zone after one year.

This is a major concern because the exclusion zone (particularly the Red Forest) has 27 years of litter (leaves and other plant material) which is a fire hazard. A large fire could redistribute the radioactive material outside of the exclusion zone.

Hope that helps.

Yeah I can't believe those deceitful bastards at the Smithsonian would dare float the idea of a possible subscription to their magazine before you read their article.

It isn't even that (at least I didn't get that). It's just a standard click through advertisement that 90% of magazine sites seem to use. A lot of interesting and informative articles are hidden away behind these pernicious, easily skippable, advertisements.

While I agree completely that it's a bit outdated(sorry, potentially putting words in your mouth) and has the potential to be pernicious(see the parent of this thread), the easily skippable part is what makes it ok with me.

I found the subscription notice to be incredibly unoffensive given the reputation of the source as well as the high quality of the article.

No worries. I keep leaving off the /s. I think we're on the same page.

You could just click it you know.
