Abstract

The contradictions found in the definitions of the roentgen as a unit of X- and γ-radiation are expounded and criticized. The definition accepted in the USSR of the roentgen as the unit of physical dose\((\frac{{OST}}{{VKS}}7623)\) differs from those in the International Recommendations and of the Congresses (Stockholm 1928 and Chicago 1937), where the roentgen is considered as the unit of dose, and not the physical dose. This has occasioned much confusion as to the physical content of the phenomena which the roentgen was intended to measure. An attempt was made in the 1953 Recommendations to resolve these difficulties, but this cannot be considered successful. The basic fault in the definition of the roentgen, which is that it “measures the amount of X- or γ-radiation” is retained. The definition given in the Recommendations of the amount of radiation as the time-integral of the intensity leads to the concept of the amount of radiation as being a flux density at a point, i.e., it adds a third variant to the dose concept, which further confuses the issue. The paper presents the requirements which the definitions of the basic units for measuring ionizing radiations — the roentgen and its equivalents — must satisfy.
