What does Alara MEAN?
a
s
low as reasonably achievablefundamental principle when threading together radiation protection and economydose minimizationwhile keeping in mind economic aspects.„Radiation protection in aviation is neither about shielding aircraft with tens of tons of lead, neither is it about flying in FL100 (about 3km high).“ Slide3

… What is Reasonably achievable?Slide5

WHAT IS REASONABLY ACHIEVABLE
new dosimeters are being developed,
existing ones optimizedSlide6

What is Reasonably achievable
Dosimeters that are already in use in other fields
can be reconfigured
or recalibrated.This makes serial production a lot cheaperand easier to have quick access to products and replacement parts.E.g. dosimeters German police uses to detect smuggling of radioactive material Slide7

What is Reasonably achievable
Dosimeter networks
equipped aircraft can measure,
downlink to ground stationuplink to not equipped aircraft.Ground stations receive a significant amount of data that can be used for flight planning and inflight rerouting purposesas well as for scientific research.Slide8

What is Reasonably achievable
Off-the-shelf-forecasts that flight crew can use without decryption
NOAA scale has deficits concerning energy levels
DLR D-scale good but not in operation (yet?)subscription to services at this time questionableVC started informing their members about solar activity via email in 2012since 2016 more ALPAs join inSlide11
ALARA in Aviation
WHAT IS REASONABLY ACHIEVABLE
information on solar activity at dispatch
education of flight crews
education of dispatcherscommander is responsible for health and wellbeing of crew and passengersneeds solid information to base their decisions onSlide12
