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.
In my cell biology class we were talking about Tay Sachâs disease. This disease actually benefits its victim by giving it resistance to tuberculosis. Its has to do with a lysosomal enzyme Î²-hexosaminidase. Tay Sachs disease Tay-Sachs disease is caused by a genetic mutation on the HEXA gene on the number 15 chromosome.It affects primarily the European Jewish population. I thought we could compare this disease relationship with that of the gene mutation in the 10% of Europeansâ immunity to HIV.n my cell biology class we were talking about Tay Sachâs disease.
