1896, in Roentgen rays "X-rays," in recognition of German physicist Wilhem Conrad Röntgen (1845-1923), who discovered X-rays in 1895. As a unit of exposure to radiation, it is attested from 1922, proposed in French in 1921.

Roentgen is the debut album by Hyde, released on March 27, 2002. It was released on his own label Haunted Records, a division of Sony's Ki/oon Records. The cover of the regular edition is an X-Ray of Hyde's own skull. "The Cape of Storms" was used as the theme song for the movie Kagen no Tsuki, which Hyde starred in.
An English version was released overseas on July 4. A Japanese release of the English version, titled Roentgen English, was released on October 14, 2004. That version came with three bonus songs that were originally used as B-side's on Hyde's singles. The limited edition of the Japanese release came with a DVD that included the music video for "The Cape of Storms" and the audio only track; "The Cape of Storms -Last Quarter Mix-".
The roentgen or röntgen (symbol R) is a legacy unit of measurement for the exposure of X-rays and gamma rays up to several megaelectronvolts. It is a measure of the ionization produced in air by X-rays or gamma radiation and it is used because air ionization can be measured directly. It is named after the German physicist Wilhelm Röntgen, who discovered X-rays. Originating in 1908, this unit has been redefined and renamed over the years. It was last defined by the US National Institute of Standards and Technology (NIST) in 1998 as 2.58×10 C/ kg, (i.e. 1 C/kg = 3876 R) with a recommendation that the definition be given in every document where the roentgen is used. One roentgen of air kerma (kinetic energy released per unit mass) deposits of absorbed dose in dry air, or in soft tissue. One roentgen (air kerma) of X-rays may deposit anywhere from in bone depending on the beam energy. This tissue-dependent conversion from kerma to absorbed dose is called the F-factor in radiotherapy contexts. The conversion depends on the ionizing energy of a reference medium, which is ambiguous in the latest NIST definition. Even where the reference medium is fully defined, the ionizing energy of the calibration and target mediums are often not precisely known.
