Dosimetric studies at the LMRI on primary standards and transfer procedures

The author describes the primary standards and transfer methods used at the Ionizing Radiation Metrology Laboratory (LMRI), and the work associated with them: calorimetric, ionometric and chemical measurements, and international standards comparisons. Outlining the current study programmes (experiments in high-energy photon and electron fields, production of standards for β-dosimetry, and future work on fast neutrons) he reaches the conclusion that the studies undertaken successively at the LMRI are closely related to the evolution of the metrological needs of users.
