Radionuclides in a sentence

Origin Natural On Earth, naturally occurring radionuclides fall into three categories: primordial radionuclides, secondary radionuclides, and cosmogenic radionuclides.

From 1958 to 1979, Florida State University conducted research on the effects of low-level radionuclides with the United States Atomic Energy Commission.

However, the radiation levels at Nyonoksa itself would surely have been of much higher—possibly releasing radionuclides into the atmosphere and drinking water that could increase cancer risk and cause other adverse health effects to those exposed.

All chemical elements have radionuclides.

All radionuclides contained in the waste have a half-life —the time it takes for half of the atoms to decay into another nuclide —and eventually all radioactive waste decays into non-radioactive elements (i.

As such, the isotope 255 Db is currently not recognised on the chart of radionuclides and further research is required to confirm this isotope.

By measuring the decay products of extinct radionuclides with a mass spectrometer and using isochronplots, it is possible to determine relative ages of different events in the early history of the solar system.

Dating methods based on extinct radionuclides can also be calibrated with the U-Pb method to give absolute ages.

Examples The following table lists properties of selected radionuclides illustrating the range of properties and uses.

However, in a few cases of odd-proton, odd-neutron radionuclides, it may be energetically favorable for the radionuclide to decay to an even-proton, even-neutron isobar either by undergoing beta-positive or beta-negative decay.

In experimental biochemistry, nucleotides can be radiolabeled with radionuclides to yield radionucleotides.

It is possible decay may be observed in other nuclides adding to this list of primordial radionuclides.

List of commercially available radionuclides This list covers common isotopes, most of which are available in very small quantities to the general public in most countries.

More than 2400 radionuclides have half-lives less than 60 minutes.

Numerous synthetic radionuclides of naturally occurring elements have also been produced in laboratories.

Other radionuclides remain radioactive for millions of years (though most of these products have so little activity as a result of their long half-lives that their radiation is lost in the background level ).

Potential health damage from exposure to radionuclides depends on a number of factors, and "can damage the functions of healthy tissue/organs.

Radionuclides and heavy metals easily sorb onto colloids suspended in water.

Radionuclides can be used to monitor processes such as DNA replication or amino acid transport.

Secondary radionuclides will occur in proportion to their half-lives, so short-lived ones will be very rare.
