Every form of technetium is radioactive. Sources of technetium Technetium is primarily obtained artificially. If technetium does exist organically, it must be in minute concentrations. Technetium ...

Paul Schaffer, head of nuclear medicine at TRIUMF, estimates that they could ship technetium to the remote town of Prince George, some 480 miles away, in about one half-life.

To avert this looming crisis, researchers in the U.S. and Canada have been racing to develop radically new technologies to produce molybdenum 99 and technetium 99m without nuclear reactors ...

The truck was en route to a Macon hospital and was carrying Technetium-99M, which is a radioactive isotope that is used in medical imaging. But just before 7 a.m., the sheriff's office says the ...

Because of their very nature, it’s impossible to stockpile these radioactive substances—they are fleeting. Technetium-99m works as a radioactive tracer because, as it decays, it flings out ...

that soak up highly radioactive materials like technetium produced during the reprocessing of spent nuclear fuel. The tiny grains of the chemical element can be tailor-made to absorb any ion ...

The ideal, therefore, is to find a radioactive substance with a short ... of a parent such as molybdenum-99 (half-life: 2.8 days), technetium-99m (half-life: 6 hours) is produced, and it ...

IN 1937, Perrier and Segrè showed that radioactive isotopes of element 43 could be formed by neutron or deuteron bombardment of molybdenum 1. Several chemical properties of element 43 were ...

Radioactive Technetium-99m is used in medicine to image the skeleton and heart and has a six-hour half-life. If it is injected into a patient and considered to be safe in 10 half-lives ...

"Francium's half-life is extremely short for a radioactive element. For comparison, technetium-99m (which is used in medical imaging) has a half-life of six hours. Uranium-235 (the type used in ...
