B Calculating safe levels of radioactivity

[Guest432]

So what do you get for the activity per gram if you convert 1.8 kBq/m³ to Bq/g?

0.0018 Bq/g

 

[mfb]

Right. A factor 100 below the 0.2 Bq/g limit.

Help

What? You figured out that all the reported values in this thread were below the safety limits all the time.

If you want to calculate some time, you'll need water with more contamination. Or take something else, e. g. mushrooms in Bavaria.

OK. I have looked now at examples from Fukushima Daichii 2011, but they're reporting the levels to now be near identical to pre incidental levels. Considering this is the largest incident since Chernobyl, is it safe to assume there have been no other incidents where water contamination was worthy to investigate?

I am considering just making a scenario and analysing that.

Water contamination is one of the first things to go down, simply because water flows away and carries the radioactivity away with it.

Mushrooms are more promising, they tend to accumulate some elements that have long-living radioisotopes.
