Light and gamma-radiation are, in some way, ‘close relatives’: both of them represent types of ‘weightless’ electromagnetic radiation, except that energy of gamma-photons is far more – at least, hundreds times as much.

Common glass, once transparent, turns brown by exposure to gamma-rays. One of the metro stations in Prague (Czech Republic) is decorated with that sort of irradiated glass tiles. However, brown is not the only option: indeed, virtually ANY color can be obtained by adding of metallic salts or oxides to a glass batch before irradiation.

Velocity of alpha-particle (at the moment it leaves nuсleus) is about 20,000 kilometers per second. Possessing such speed, one would be able to fly around the Earth’s equator in just two seconds.

Radioactively labeled banknotes (‘hot money’), which appeared in one of James Bond movies, are not fiction. Intelligence agencies of some countries actually use it to track ‘criminal’ money. Needless to say that contamination levels are low and do not pose direct threat to health (of course, if you are not going to eat them).
Mass ratio of atom to cat is the same as that of cat to the Earth.
At present time radio-diagnosis and radiation therapy are used to treat not just humans, but also pets and other animals.

Some gemstones, as a common glass, can change color under radiation exposure. Good example is irradiation of topazes that results in deepening of their natural color and obtain rare tints. Of course, such enhancement raises price of a jewelry.

World’s most expensive element is californium or, more precisely, its isotope californium-252. One gram of this isotope costs like a few hundred kilograms of gold! There are only two places in the world where it is regularly produced. One of them is Dimitrovgrad, Ulyanovsk region in Russia.

Velocity of fast neutrons emitted during nuclear transformations is 17,000 times more than that of a bullet shot out of a sniper rifle.

t is known that natural color of topaz is determined by crystalline imperfections resulted from million-year exposure to natural sources of radiation, i.e. cosmic and terrestrial radiation. However, sunlight exposure leads to slow discoloration of these stones.
Diameter ratio of atom to hair is the same as that of hair to large Ferris wheel.
Technically, radiation dose that one gets during fluorography examination of chest may be compared to dose a person receives from eating about 500 bananas. These healthful fruits contain increased amount of natural radioactive isotope potassium-40, – but, of course, this doesn’t mean that bananas represent any kind of radiation hazard.

Atomic nucleus is very, very dense. ‘Ping-pong’ ball filled with pure nuclear matter would weigh as much as 10 billion tonnes. It is more than 1,500 Great Pyramids of Giza (Pyramids of Khufu) put together.
If one puts a wheat grain on a plate of ordinary weighing scale, then it can be balanced by such number of atoms that similar quantity of grains would weigh same as a rather big asteroid. And it would take around 3 million years to count these grains over.
Radioactive element radium became the first tool of nuclear medicine. In early 20th century its price skyrocketed: cost of 1 gram of radium was equal to 160 kilograms of gold!

The radiation therapy was used for the first time in the early 20th century. In 1901 French physician Henri-Alexandre Danlos became the first professional to use recently discovered radium for treatment of skin diseases.
