[Binary Numeral System] Numerical system based on two different states, usually represented by the two symbols 0 and 1. Information storage and processing in modern computers is based on this system. Here the smallest unit is a bit.

See Bit, Byte.

Eight bits are grouped together to form one byte, additional one start and one stop bit.

The (spot) compression of for example breast tissue, allows for greater reduction in thickness of the area of interest and improved separation of breast tissues by the use of a small compression device.
Compression can be also a software or hardware process that shrinks images to lessen the storage space. Compression is generally accomplished by removing the bits that define redundant like data blank spaces, and replacing them with a smaller symbolic code that represents the removed or redundant bits.

In the internal conversion process the multipole electric field of the nucleus of an atom, in an electromagnetically excited state, react with an orbit electron. With enough energy the electron is ejected (internal conversion electron). The energy of the conversion electron depends on the energy transferred from the nucleus reduced by the shell specific binding energy. This process competes with gamma emission. The refilling for the vacancy left by the internal conversion electron occurs through the Auger effect, a higher orbit electron take place and x-ray or an Auger electron will be emitted.
The atomic number of the atom gets not changed by internal conversion.

(ARS) The acute radiation syndrome is a form of radiation sickness. An acute radiation syndrome can be developed after the exposition to a high radiation dose received in a short period of time (e.g., x-rays or gamma rays). ARS subsyndromes include hematopoietic, cutaneous, gastrointestinal, and neurovascular diseases. The reaction will vary with dose and factors like age, medical co-morbitdity and immunosuppression.
