All other polonium isotopes are short-lived except polonium-210 (half-life about 138 days), which is the most commonly used isotope. It is prepared by bombarding bismuth with neutrons in a nuclear reactor.olonium has 34 isotopes, more than any other element. All of these isotopes are radioactive. The most stable, polonium-209, has a half-life of about 103 years. Polonium-208 (half-life about 3 years) is the only other polonium isotope with a half-life over one year.
Ashkenazi Jewish genetic diseases are a group of rare disorders that occur more often in people of Eastern European (Ashkenazi) Jewish heritage than in the general population.
Also part of the evidence is that no Semitic people ever suffer from Tay-Sachs disease! The Jewish people of the Arab East regions never ever suffer from Tay-Sachs disease. Tay-Sachs disease is particularly common among Jewish people of Eastern European and Russian (Ashkenazi) origin. About one out of every 3,600 babies born to Ashkenazi Jewish couples will have the disease. (Medical dictionary on Tay-Sachs disease) Now this begs the question âwho then are the Ashkenazi Jews?â Why this question? Because . 90% of the worlds Jewry is of European Ashkenazi Jews . 95% of North American Jewry consists of, came from European Ashkenazi Jews. So all the Ashkenazi Jews are not even of the Semitic blood line, of Shem, but of Japheth . Gen 10:1 Now this is the genealogy of the sons of Noah: Shem, Ham, and Japheth. And sons were born to them after the flood. Gen 10:2The sons of Japheth were Gomer, Magog, Madai, Javan, Tubal, Meshech, and Tiras.
