The scientists emphasize that LENR reactors are very different from the fission reactors employed today, which use highly radioactive elements, produce radioactive waste, and occasionally suffer from meltdowns.
FORBES: NASA: A Nuclear Reactor To Replace Your Water Heater
Rare earth minerals are often mixed with radioactive elements, and processing creates low-level radioactive waste.
In 1911, Marie Curie received her second Nobel prize for her work on radioactive elements.
Radioactive elements - such as uranium - are unstable and break down over time.
The news that radioactive elements are present in small amounts in some food seems ominous.
Similar generators with radioactive elements are known to litter remote parts of Russia.
In the modern world, some hope to use green rust to remove toxic metals and radioactive elements from the environment.
It uses two ion exchange processes to remove the radioactive elements Cesium-134 (Cs-134), Cesium-137 (Cs-137) and Strontium-90 (Sr-90) from the seawater.
FORBES: Major Milestones Passed At The Fukushima Daiichi Nuclear Power Plant
And lead is about as heavy as it gets before elements become routinely radioactive and thus inappropriate for all but specialised applications.
It also found no threat from the warmer water that is discharged back into the river or from any radioactive elements escaping from the plants into the Hudson.
The second utilizes a highly selective media to capture more radioactive elements in the presence of ions other than sodium, such as potassium, magnesium, and calcium, also through ion exchange process.
FORBES: Major Milestones Passed At The Fukushima Daiichi Nuclear Power Plant
Although there were no machines for detecting them systematically before 1935, cosmic rays have left their footprints in the geological record by creating radioactive elements such as the carbon-14 used in carbon-dating.
Duke Energy spokeswoman Rita Sipe said Duke Energy had detected trace radioactive elements, likely to have originated from Japan's Fukushima plant, in North Carolina and South Carolina -- but at a level "far below" reporting requirements.
CNN: Japan's nuclear contamination spreads to more U.S. states
Joseph De Trani, former head of the National Counterproliferation Center, predicted U.S. intelligence would determine the size and composition of the nuclear device in one to three days based partly on radioactive elements released into the environment.
Tepco is developing a few measures, including a system that would pump groundwater away from the reactor buildings so there would be less contaminated liquid to deal with, and another that would remove all radioactive elements from the water so it could be released safely into the environment.
Each has its own decay pattern and as they decay, they become other elements that move to other places in our bodies and can be toxic as well as radioactive.
