An updated overview at the difficulties in the implementation and dissemination of the dosimetry secondary standards

A basic element to achieve the measurement traceability is the correct implementation and dissemination of the measurement standards. In the case of dosimetry, there are internationally harmonized calibration methods; however difficulties may arise in their introduction related to the technical characteristics of the standards and the methods described in the technical documents. The use of commercially available dosimetry systems as secondary standards requires the personalized studies of their technical characteristics. The recommended methods do not always compatible with the available infrastructure and modifications are needed. The article makes a critical analysis of the implementation of the dosimetry secondary standards in the international arena based on the identified difficulties.
