By 1934, Fermi had bombarded heavier elements with neutrons to induce radioactivity in elements of high atomic number.

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

Dr Nahrul assures that unlike neutrons, gamma rays are incapable of inducing radioactivity in materials exposed to them.
14.
One may harbour doubts as to whether irradiation will induce radioactivity in the food and whether it is safe.
15.
By 1934 Fermi had used neutrons to induce radioactivity in 22 different elements, many of these elements of high atomic number.
16.
In January 1934, Ir�ne Joliot-Curie and Fr�d�ric Joliot announced that they had bombarded elements with alpha particles and induced radioactivity in them.
17.
A related problem for a future commercial fusion power station is that the neutron bombardment will induce radioactivity in the reactor material itself.
18.
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.
19.
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.
20.
However, the discovery of induced radioactivity by P, Fermi realized that using neutrons, which have no electrical charge, would most likely produce even better results than the positively charged alpha particles.
