Element Number 118 According to the Periodic Table of Radioactivity, at this time the most radioactive element known to man is element number 118,Oganesson. The decay rates for the latest man-made elements are so fast that it's hard to quantify how quickly they break apart, but element 118...
In comparison, the most radioactive element is polonium. It has a half-life of a mere 138 days. Still, uranium has explosive potential, thanks to its ability to sustain a nuclear chain reaction. U-235 is "fissile," meaning that its nucleus can be split by thermal neutrons — neutrons wi...
Deep below the ground,radioactive elements break up water molecules(分子),producing ingredients that can fuel subsurface life.This process,known as radio-lysis(辐射分解),has sustained bacteria in isolated,water-filled cracks on Earth for millions to billions of years.Now a study published in Astro...

This substance is the most radioactive natural element, a million timesmore sothan uranium. It is so radioactive that it gives off a pale blue glow. Yet it would still take the Curies another three years to produce a pure radium salt. Having originally worked with 100g of the ore, equiv...

Plutonium is the 94th element in the periodic table and one of the most dangerous elements on Earth. Here we explore Plutonium in more detail.
For Exercises, use the following information.Thehalf-life of a radioactive element is defined as the time that it takes for one-half a quantity of the element to decay. Radioactive Carbon-14 is found in all living organisms and has a half-life of 5730 years. Archaeologists use this ...

A radioactive suture for inhibiting an intimal hyperplastic response comprises a needle and a suture material having a radioactive beta-emitting element. This radioactive element is preferably chemically bonded to an organic substrate of the suture material. It is preferred that the radioactive suture...
