Objectives

• Evaluation of status of operational implementation of Art. 42 of BSS

• Degree of harmonisation• Differences in transposition:

– Choice of dose limits and constraints– Procedures for exposure assessment– ALARA below limits– Reporting requirements– Inspection and enforcement

Information channels

• Radiation protection authorities (RP)• National civil aviation authorities

(CAA)• Airlines (AL)

Country specific information

• 32 countries (27 EU member states + Croatia, Macedonia, Norway, Switzerland and Turkey)

• Information– Legislation– Dose register– National practice

Methods for dose assessment

• Dose calculation by software packages• CARI 6 and EPCARD most frequently

used• Rarely pre-calculated tables for flight

schedules• Only a few airplanes (in Germany)

equipped with on-board measurement equipment

Dose registration

• No registration for frequent flyers• No uniform way of information on doses to personnel

Conclusions

• Appropriate legislation implemented• Harmonisation:

Need for guidance:– Treatment of dose limits and constraints– Employment of freelancers – Crew members working for different

airlines

(future) Important role for EASA

Remark on EASA and

harmonisation

• Regulation EC 216/2008: uniform application of common rules
