Po is concentrated in most marine organisms by factors of 10-10 relative to seawater concentration and its accumulation varies from one tissue to another, according to the capacity to concentrate polonium (Carvalho, 1988). This radionuclide gives rise to almost 7% of the dose equivalent, through natural radiation intake (UNSC, 1988) and about 77% of daily intake comes from solid food, mainly se...
At the time of publication, the remains of Yasser Arafat have been exhumed and are being investigated for cause of death as a result of the fi ndings of the case reported here.

We performed both a laboratory and a field intercomparison of two novel glass-based retrospective radon detectors previously used in major radon case-control studies performed in Missouri and Iowa. The new detectors estimate retrospective residential radon exposure from the accumulation of a long-lived radon decay product, (210)Pb, in glass. The detectors use track registration material in dire...
Polonium-210 is an alpha particle emitting radioactive element with a half-life of 138 days. It appears at the end of the decay-chain of Uranium-238 where the long lived Lead-210 (22.3 a) decays to Bismuth-210, and finally Polonium-210. Po is introduced into the biosphere through various routes of terrestrial and marine radioecological pathways. The level of Po activity in drinking water (5 Bq....
