[X-ray format and dose (author's transl)]. 1978

H J Maurer

The paper discusses conventional roentgenographic methods and image amplifier fluorography. 1. Reduction of the required dose in conventional roentgenographic examinations has been achieved by the use of CaWO4 special foils, or , to an even greater extent, on rare earth basis (lanthanum oxibromide). 2. A considerably greater reduction in dose is achieved with image amplifier fluorography of medium format. 3. The possibilities offered by both systems are discussed. Possible future developments are examined.

D011829	Radiation Dosage	The amount of radiation energy that is deposited in a unit mass of material, such as tissues of plants or animal. In RADIOTHERAPY, radiation dosage is expressed in gray units (Gy). In RADIOLOGIC HEALTH, the dosage is expressed by the product of absorbed dose (Gy) and quality factor (a function of linear energy transfer), and is called radiation dose equivalent in sievert units (Sv).
