Research on the relationship between the scattering contribution and physical factors of the reference radiation regulated by ISO 4037-1.

PLoS ONE, 2022
In the latest version of ISO 4037-1:2019 standard, the minimum dimension of a gamma radiation reference field was not clearly specified, which makes the construction of a minitype gamma reference radiation field lack of scientific basis.
