Exemption & Authorisation Limits

February 20th, 2018
by Joseph Magill

Based on the recently released Swiss RPO data (January 2018), this new Nucleonica application provides data on exemption and authorisation limits for radioactive materials. Based on assessment values for dose coefficients for ingestion and inhalation, together with specific dose rates at various tissue depths for external radiation (h10, h0.07, and hc,0.07), values are given for the operational radiation protection quantities together with exemption and authorisation limits and guidance values.
EandA-AvIn summary, the application has the following main features:
– Based on the dose coefficients for ingestion and inhalation, together with specific dose rates at various tissue depths for external radiation (h10, h0.07, and hc,0.07), exemption limits LE, authorisation limits LL, and guidance values for airborne CS and surface contamination CS are given.
– From the above quantities, and the user specified activity (Bq) and surface contamination (Bq/cm2), the total doses for ingestion, inhalation and external radiation (H10, H0.07, and Hc,0.07) are calculated.
– The latter quantity, Hc,0.07 allows the user to calculate the dose rate to skin following a spill of radioactive material.
– a table of the Swiss Operational radiation protection data is provided together with links to the corresponding web pages in French and Germany are given.
