D-values are used by the Environment Agency (EA), SEPA and the UK police advisers (CTSA) to determine the source category and appropriate security measures for sealed sources, where this cannot be assessed directly from the use/practice. D (Danger) values are in TBq, and the quotient A/D (where A is the activity of a source in TBq) are used to determine source category. In the UK some sources are already categorised for security and this will then take precedence over A/D. For those into dosimetry calculations and assessments behind D values, section 3 onwards explain in detail how the values are derived.

This link takes you to an extensive database which compiles general data on radiological accidents/incidents and other events which have produced radiation casualties. Listed events include acute radiation causalities, chronic radiation injury and accidents releasing large quantities of radioactive materials. The resource is very interesting but we do not warrant its accuracy in anyway.

EPCARD stands for 'European Program Package for the Calculation of Aviation Route Doses'. This comprehensive online calculator is produced by the GSF-National Research Center for Environment and Health (Germany). You can calculate cosmic radiation dose received en route between any two airports (on any given day), or the dose rate in the plane for a given elevation and position.

The current UK position with respect to the transport of radioactive materials by road is to follow the ADR. This is driven by The Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations 2009.

'New' guidance (2013) for businesses and individuals who have to handle naturally occurring radioactive substances (NORM). Guidance not intended for anyone who is using NORM for its radioactive, fertile or fissile properties. This resource is still valid but may be updated in time due to an updated UK wide radioactive substances exemption document released in August 2018. [Also applies in Wales and Scotland]

This guidance is for medical and veterinary uses of radioactive sources and applies to the whole of the UK. It was written in 2011, but still complies with the latest environmental legislation for radioactive substances. Under some circumstances, the use of small amounts of radioactive material in the medical and veterinary sector is exempt from the requirement to have a permit (or authorisation) provided certain conditions are met.
