Roentgen also revealed that these X - rays could pass through solid matter and expose an X - ray film.
(2) This discovery led immediately to the use of X - rays in medicine, a use we are all familiar with.
Although Roentgen discovered the properties of X - rays he did not know what the rays were.
He therefore called them X - rays, the X standing for their unknown nature.
Today scientists know X - rays to be electromagnetic radiation of extremely high frequency and therefore of extremely short wave length.
X - rays are considered to be produced whenever rapidly moving electrons bombard any solid material.
The greater the atomic weight of the material, the more plentiful the X - rays, the greater the speed of the electrons the higher the frequency of the X - rays.
As mentioned above X - rays were in a wide use for diagnostic purposes in medicine since their discovery.
Industrial radiology has been discovered later particularly for inspecting welds and castings in the automobile and airplane industries.
Flaws and cracks inside the metal are readily revealed due to the use of X - ray techniques.
Famous paintings are often X - rayed to determine whether they are the originals or forgeries.
(3) Using X - rays irradiation the scientists have learnt to change structures of well - known materials such as metals, ceramics, etc.
They could obtain materials of greater strength with higher melting point and particular electrical properties.
Radiation is known to be a mutagenic agent.
In microbiology mutations are increased by irradiation.
When a large - scale production of penicillin was introduced the best strain yielded 100 - 200 units of penicillin.
Being irradiated with X - rays, the same strain produced more than 1, 000 units.
Many new uses have been found for this treatment in agriculture.

There are many islands in the South Pacific.
These are tropical islands.
The weather is warm all year round.
The trees on the island in the picture are coconut palms.
They are very useful because they grow well in sandy and salty places near the seashore where other kinds of trees can't grow.
The coconuts give food.
The islanders can dry the nuts and sell them to make oil.
They can also use the trunks of the trees for building and the leaves for making roofs for their houses.

A photograph that changed the world This is the first X - ray photograph.
It was taken by a German scientist, Wilhelm Konrad Roentgen, in 1896.
It is his wife's hand.
The bones in her hand (and also her wedding ring!
) are clearly seen in the photo.
X - rays were discovered by accident, while Roentgen was experimenting with electricity.
Soon after, he built the first X - ray machine.
Immediately, hospital operations were made much safer.
For the first time, doctors could see inside people's bodies before they cut them open!
In 1901, Roentgen was awarded the very first Nobel Prize in Physics.
His invention is still used every day by doctors and dentists, and is called the window into the human body.
Since the intoduction of computer imaging in the 1970s, X - ray machines have been used for other things, too.
At airports, many criminals have been caught with illegal items in their luggage.
Also, lost works of art have been discovered underneath other paintings.
In factories, many faults in new products are found every day, using X - rays.
There is no doubt that new uses for X - rays will be developed in the future.

Depletion of the Ozone Layer The protective layer of the Earth, the ozone layer, which protects the Earth from the sun's destructive UV (ultraviolet) rays, is being damaged by CFCs (chlorofluorocarbons).
They are released by the daily use of industrial and household products : refrigerators, air conditioners, foam insulation, cleaning chemicals, food packaging.
In the ozone layer they attack the ozone molecules making a «hole».
This «hole» allows more UV rays to penetrate to the Earth.
It increases the risk of skin cancer, weakens the immune system of people.
Besides, UV rays influence the oceans, the growth of plankton, an essential part of the marine - life food chain in the negative way, reduce economically important - crops (rice, cotton, soy beans).

Рентген также показал, что эти рентгеновские лучи могли проникать сквозь твердую материю и подвергнуть рентгеновской пленки.
(2) это открытие сразу же привело к использованию рентгеновских лучей в медицине, применение мы все знакомы.
Хотя рентген открыл свойства рентгеновских лучей, он не знал, что лучи.
Поэтому он назвал их x - лучи, Икс, стоящего за их неизвестной природы.
Сегодня ученые знают рентгеновские лучи, электромагнитные излучения крайне высоких частот и, следовательно, чрезвычайно короткая длина волны.
Рентгеновские лучи считаются произведенными, когда быстро движущиеся электроны бомбардируют любой твердый материал.
Чем больше атомный вес материала, тем больше рентгеновских лучей, чем больше скорость электронов, тем выше частота рентгеновских лучей.
Как уже упоминалось выше, рентгеновские лучи были в широком использовании для диагностических целей в медицине с момента их открытия.
Промышленная радиология был обнаружен позже, особенно для контроля сварных швов и литья в автомобильной и авиа промышленности.
Недостатки и трещины внутри металла легко раскрывается благодаря использованию рентгеновской технике.
Известные картины часто рентген, чтобы определить, являются ли они оригиналами или подделками.
(3) используя рентгеновское излучение ученые научились изменять структуры известных материалов, таких как металлы, керамика и т.
Д. Они могут получить материалы большой прочности с высокой точкой плавления и особые электрические свойства.
Радиация, как известно, был агентом мутагенные.
В микробиологии мутаций возрастает при облучении.
Когда был введен крупномасштабного производства пенициллина лучшей нагрузку дали 100 - 200 единиц пенициллина.
При облучении рентгеновскими лучами, тот же штамм произведено более 1 000 единиц.
Много новых применений были найдены для этой обработки в сельском хозяйстве.
