226 Ra occurs in the decay chain of 238 U (often referred to as the radium series). Radium has 33 known isotopes from 202 Ra to 234 Ra. In 2013 it was discovered that the nucleus of radium-224 is pear-shaped. Radium (Ra) 226 Radioactive Isotope Decay Calculator Online radioactive decay calculator that allows you to find out the radioactivity decay in Radium (Ra) 226. Note: The calculation of radioactivity in minerals is based on certain assumptions. Radium (Ra) 226 Isotope Radioactivity Decay Calculation Radium-226 is a source material for producing Radon-222 in radiotherapy treatments (Radon-222 is safer to use because of its much shorter half-life of 3.8 days). The radiation from radium can cause lung cancer, osteogenic sarcoma, blood dyscrasias and injury to skin.
