Bismuth radioactivity
Web2 days ago · The radiation shielding properties of telluro-borate glasses have a great importance in nuclear industry. This work focused on the study of the glasses of the (70-x)B 2 O 3-5TeO 2-20SrO-5ZnO-xBi 2 O 3, (with 0≤x≤15% mol%) system, which have been synthesized by the melt-quenching route.The scanning electron microscope (SEM) … WebHowever, if you had a 1 kg block of radioactive material containing approximately 10 25 Bismuth-210 atoms instead, then you could be nearly certain that some of the radioactive isotopes would decay. If it takes five days for the count rate of the sample to be halved, then you know that the half-life of Bismuth-210 is five days.
