What unit is the Qinlun and what unit is the Roentgenium

Roentgen is a radioactive substance.

One unit of the amount of irradiation produced. It is named after the German physicist Wilhelm Konrad Röntgen.

Wilhelm Conrad R NTGEN), adopted in 1928. The English code is R.

In 1895, the Institute of Physics in Phischburg, Germany.

Director and professor of physics Wilhelm Konrad Röntgen put the newly discovered electromagnetic waves.

Named X-ray, the "X" means something that cannot be understood. In order to pay tribute to the inventor, the world also called it the "Roentgen line". X-rays are a type of electromagnetic wave or radiation with energy.

Zenlun is a unit of radiation in honor of the German physicist Wilhelm R Ntgen, who discovered X-rays.

1 Qinlun is at a standard atmospheric pressure.

Under the amount of irradiation required to create a unit of electrostatic electricity in 1 cubic centimeter of air at 0 degrees Celsius for positive and negative ions.

The unit "R ntgen" is used to measure the amount of radiation to radioactive material, and this unit is usually denoted as R. This was erected in honor of the German physicist Wilhelm R Ntgen, who discovered X-rays. 1 Chinlun is the amount of positive and negative ions in the electrostatic unit created in 1 cubic centimeter of air at 0 degrees Celsius at a standard atmospheric pressure.

X-ray radiance.

In 1895, William Konrad Röntgenium, director and professor of physics at the Fort Physics Institute in the Philippines, described the newly discovered electromagnetic waves as X-rays, and the meaning of this "X" is unintelligible. In order to show respect for the inventor, the world also calls it the "Qinlun Line".

The amount of radiation, don't know these things, the encyclopedia should have.

Roentgenium (r) is the unit of irradiation, 1r = c kg.

1 Roentgen corresponds to 1 electrostatic unit each of the positive and negative ionic charges generated in 1 cubic centimeter of standard air (mass in grams).

Roentgenium is defined as: the formation of positive or negative ions in air with a total charge of 1 cm -3 mass of dry air at atmospheric pressure equivalent to 0 and 760 mm Hg at 1rx or radiation irradiation. The amount of irradiation is only for air and only for X-rays or rays.

At the time of the nuclear accident in the USSR "Chernobyl", the unit adopted was "Roentgenium", which was equal to 10 "millisieverts". i.e.: 1 sievert = 1000 millisieverts; 1 mSievert = Roentgen = 1000 microsieverts.

Roentgenium is a unit of irradiation, and 1 roentgen is equivalent to 1 electrostatic unit each in 1 cubic centimeter of air (mass in grams) in a standard condition of 1 cubic centimeter.

Roentgenium's English code name is R, which is defined as 1 cubic centimeter of air at 0 degrees Celsius, 760 mm Hg air pressure, resulting in 1 electrostatic unit (?).10 coulombs) radiant intensity of positive and negative ions = 1 roentgen unit.

Roentgenium units are not SI units, but they are still very commonly used in medical and other fields, and the conversion to SI units is 1 Roentgen unit = coulomb kilogram.

The amount of radiation indicates the radiation dose of the spatial distribution of the radiation, that is, the amount of irradiated radiation of the substance at a certain distance from the radioactive source, and is expressed as the amount of electric charge generated by the X-ray or Y-ray remaining in the air.

It is important to note that the amount of radiation is only used when photons cause ionization in the air, and other types of radiation, although they can also cause ionization in the air, do not allow the use of the amount of irradiation.

The origin of Roentgen rays is closely related to a famous German physicist, his greatest achievement is the discovery of X-rays, which paved the way for the pioneering medical imaging technology, which can be said to be a pioneering feat for the medical community, so in 1901, he was awarded the Nobel Prize in physics, and this invention has also influenced many other important fields.

To this day, in honor of the achievements of the famous German physicist, X-rays are named after him, known in many countries as Roentgen rays, and the chemical element Rg, No. 111, is also named after Roentgenium.

Roentgenium (r) is a non-statutory unit whose irradiation has been abolished, 1r = .

1 Roentgenium corresponds to 1 electrostatic unit each of the positive and negative ionic charges generated in 1 cubic centimeter of air (mass in grams) in a standard crude imitation condition.

Roentgenium's fixed-scale ruler is defined as the formation of positive or negative ions in air with a total charge of 1 cm -3 of dry air at atmospheric pressures equivalent to 0 and 760 mm Hg under 1r x or ray irradiation. The amount of irradiation is only for air and only for X-rays or rays.

At the time of the nuclear accident in the USSR "Chernobyl", the unit adopted was "Roentgenium", which was equal to 10 "millisieverts". i.e.: 1 sievert = 1000 millisieverts; 1 mSievert = Roentgen = 1000 microsieverts.

German, discoverer of X-ray 100 years ago, the world's first Nobel laureate in physics.
