Nuclear power, many people think, is inseparable from a volatile, invariably lime-green, mutant-making radioactivity.
In 1898, the Curies obtained a new element, whose radioactivity was several million times stronger than that of uranium.
The owner of the power station confirmed that the fire did not cause any damage to the reactor and there was no radioactivity involved.
Better still, it became apparent to him that one could use radioactivity as a clock, with the half-life of a decay series enabling us to calculate the age of a rock.
She named the other radium. She measured the amount of radioactivity, an atomic property, and felt that the radioactivity was proportional to the amount of the element.
You can make a mess but you're not gonna have a major release of radioactivity.
However, unlike the simple exponential that describes radioactivity, which has only one variable, a stretched exponential describes a process controlled by several independent factors.
For instance, because it takes only 8 days for the radioactive isotope iodine-131 to decay away to half its original level of radioactivity, simply waiting should be a fix.
equipment used to treat diseases with x-rays or radioactivity.
Impounded food is buried, and tainted milk is diluted to acceptable levels of radioactivity and sold to consumers, she says.
The transportation and transformation of 14 C phenanthrene in a closed 'plant lava nutrient solution air' chamber system was studied by using radioactivity technology.
"It is the product of radioactive decay (see radioactivity) and is used in helium dating. It is used as an inert gas in welding, rocket propulsion, balloon flight, hyperbaric chambers, deep-sea diving (see nitrogen narcosis), gas chromatography, luminous signs, and cryogenics."
Boffins were busily filling in the blanks in the periodic table and probing unknown atomic phenomena (like radioactivity and bonding).
Article 49 materials containing radioactivity in excess of standards or materials containing toxic and harmful substance easy to dissolve in the water may not be used in a Marine construction project.
Cancer is no longer an incurable disease nowadays, it can be remedied by using radioactivity.
In 1896, Henri Becquerel had inadvertently discovered radioactivity when he left some uranium ore in a drawer on top of an undeveloped photographic plate, on which the uranium left a "shadow."
The timber and other building materials have been buried in the sandy soil to reduce the amount of radioactivity dispersed by wildfires.
According to the safety behavior of nuclear district heating reactor, the calculation method of accidental release of radioactivity is derived.
The first is the internal heat produced by radioactivity inside the earth. The second is the external heat supplied to the earth by the sun.
The level of radioactivity in the soil was found to be above recommended limits.
Radioactivity cannot contaminate food that is packaged; for example, tinned or plastic-wrapped food is protected from radioactivity as long as the food is sealed.
