Half of 238
WebA characteristic constant is the half-life of radioactive substances. It is the time taken for a given amount to be reduced by half due to decay and, therefore, radiation emission. You may also wonder, "What is the half-life of U 238?" 4.5 billion years It is also important to understand why we use half-life. WebUranium-238 (238 U or U-238) is the most common isotope of uranium found in nature, with a relative abundance of 99%. Unlike uranium-235, it is non-fissile, which means it cannot sustain a chain reaction in a thermal …
