[ RadSafe ] Po-210 in the news

[Hill, Peter]

Steven,

Po-210 contents are usually assessed by means of alpha-spectroscopy. LOD's of 1 mBq/l are achievable. At CIMB-J already a level of 0.4mBq Po-210 may be detected in a 24h-sample of urine. Just routine.

Kind regards

         From the Jerusalem Post article linked below:

"And yet, eight years after Arafat’s death, the
Swiss scientists reported finding polonium levels
of 54 millibecquerels (mBq) and 180
millibecquerels on his belonging, considered to be high levels."

         By my reckoning, the former is 0.001
pCi, and the latter is 0.005 pCi.  If that is
correct, how can levels this low be
detected?  The error bars must be huge. . . .
