1. The Lette Verein
In the year 1866 William Adolf Lette created the "association for the promotion of the earning power of the female sex", which after his death 1868 in "Lette Verein" one renamed.
Starting from 1872 under the direction of Anna Schepeler Lette, becomes the association school carrier and offers after short time a multiplicity at training for women. It works thereby innovative for the promotion of the woman gainful employment. On 18 October 1902 the building Viktoria Luise Platz 6 monument-protected today is referred in Schöneberg. This building was sketched by the well-known architect Alfred Messel. After that 1984 the new building of the laboratory building in the Geisbergstrasse 34 were referred, present themselves the Lette Verin today as steeped in tradition education place, which offers occupation training eligible for low financing on high level.

2.) History
The final covering of the X-ray is mostly attributed to William Conrad Roentgen. That was to 28.12.1895. It is considered however as safe, that already different before it to X-ray produced e.g. Johann Hittorf, William Crookes, Heinrich Hertz and his pupil Philipp Lenard as well as Nikola Tesla. Since the scientists mentioned however does not admit its knowledge gave, also Roentgen did not know anything of it. Thus he discovered the X-ray independently, when he observed fluorescent light with the enterprise of the cathode ray tube. First Nobelpreis for physics was lent to it in the year 1901, whereby the Nobelpreiskomitee the practical meaning of the discovery out main headers. 1896 the French physicist Beoquerel discovered the natural radioactivity of uranium. In the same year developed the first x-ray tube with adjustable Vakuum. Radium will be by the married couple Currie was proven 1898.

3.) The 4 fields of the radiology:
In the nuclear medicine the patient gets a radioactive Substans intra venously squirted. Thus the patient radiates it is present however no health endangerment. Thus metabolic achievements of the organism can be seized, measured and represented figurativy.

With the radiotherapy it does not concern the treatment more maliciously and malicious illnesses. By radiation or chemotherapy. E.g. Tumore are treated. In the year 270000 - 300000 humans in Germany gets sick at cancer (soll krebs heißen bitte überprüfen).

In the Radiodiagnostics bones or organs are figurativy represented by radiate. During the representation of organs frequently contrast means used thereby are determined e.g. fractures.

A further task of a MTA is to be evaluated it the measuring instruments and logged it. This is made in the dosimetry. It is put large worth on the radiation protection of the patients, the personnel and more indifferently third persons.
