induced radioactivity

It was this gas that must have produced the induced radioactivity noted by the Curies.

Some induced radioactivity is produced by background radiation, which is mostly natural.

This observation led to the use of induced radioactivity for the identification of elements.

The conditions inside certain types of nuclear reactors with high neutron flux can cause induced radioactivity.

Induced radioactivity occurs when a previously stable material has been made radioactive by exposure to specific radiation.

I thought maybe some particles would come through and leave residual decaying nuclei here, induced radioactivity."

Detractors of food irradiation have concerns about the health hazards of induced radioactivity.

This induced radioactivity might be the result of the impingement of radiations upon the substance.

With shielded spacesuits they were able to mine its substance for four or five months before heat and rising induced radioactivity drove them off again.

Since a very small amount of neutrons is produced, there would be little induced radioactivity in the walls of the fusion chamber.

The elements most important for induced radioactivity for sea water are sodium-24, chlorine, magnesium, and bromine.

Neutron activation is the main form of induced radioactivity, which happens when free neutrons are captured by nuclei.

That gives you induced radioactivity."

Fermi won the 1938 Nobel Prize in Physics for his work on induced radioactivity.

Also, it's apparently seen an intense radiation environment-- there's low-level induced radioactivity, cosmic ray tracks, and so on.

It must be composed of elements with low neutron capture cross sections to prevent positive void coefficient and induced radioactivity.

Further work by Enrico Fermi in the 1930s focused on using slow neutrons to increase the effectiveness of induced radioactivity.

Nagchaudhuri's research focused on nuclear isomers, induced radioactivity, Cherenkov radiation and nonthermal plasma.

There is also a risk of induced radioactivity caused by neutron activation, which is a major source of noise in high energy astrophysics instruments.

However, since natural radiation is not very intense in most places on Earth, the amount of induced radioactivity in a single location is usually very small.

If they had left the counters on they would have discovered that some substances emitted high-energy particles for a long time afterward--artificially induced radioactivity.

In 1938, Enrico Fermi escaped fascist Italy after winning the Nobel prize for his work on induced radioactivity.

This Induced radioactivity was discovered by Irène Curie and F. Joliot in 1934.

Induced radioactivity increases the amount of nuclear waste that must eventually be disposed, but it is not referred to as radioactive contamination unless it is uncontrolled.

In 1934, Irène Joliot-Curie and Frédéric Joliot bombarded elements with alpha particles and induced radioactivity in them.
