The main risk of exposure to depleted uranium is chemical poisoning by uranium oxide rather than radioactivity ( uranium being only a weak alpha emitter ).
12.
An alpha emitter ( 106Te ) was discovered with a potential energy surface on which the alpha-decay valley may be seen by the same method.
13.
Beside a chemical contamination, 249 Cf, being an alpha emitter, brings undesirable self-damage of the crystal lattice and the resulting self-heating.
14.
Radioactive contamination may also be an inevitable result of certain processes, such as the release of radioactive xenon in alpha emitters please see actinides in the environment.
15.
This means that the observation of 266 Sg as a long-lived alpha emitter is retracted and that it does indeed undergo fission in a short time.
16.
The only site I know of to get radioisotopes seems to only offer Po-210 as its alpha emitter, so I might be stuck with that.
17.
Besides a chemical contamination, 249 Cf, as an alpha emitter brings undesirable self-damage of the crystal lattice due to the resulting self-heating.
18.
In the past the neutron trigger for an atomic bomb tended to be beryllium and a high activity alpha emitter such as polonium; an alternative to polonium is Pu-238.
19.
The powerful alpha emitter polonium-210 ( a milligram of 210 Po emits as many alpha particles per second as 4.215 grams of Alexander V . Litvinenko in 2006.
20.
Alpha radiation is an average of about 20 times more dangerous, and in experiments with inhaled alpha emitter up to 1000 times more dangerous, than an equivalent activity of gamma emitting radioisotopes.
