ALARA in Aviation

2. ALARA in Aviation What does Alara MEAN?
as low as reasonably achievable
fundamental principle when threading together radiation protection and economy
dose minimization
while 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).“

So…
… What is Reasonably achievable?

5. ALARA in Aviation WHAT IS REASONABLY ACHIEVABLE
new dosimeters are being developed,
existing ones optimized

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

7. ALARA in Aviation What is Reasonably achievable Dosimeter networks
equipped aircraft can measure,
downlink to ground station
uplink to not equipped aircraft.
Ground stations receive a significant amount of data
that can be used for flight planning and inflight rerouting purposes
as well as for scientific research.

SAFESKY
US-based
multi-party
Europe considers an „action plan“ following that same path. That’s a good start - but long overdue!

9. ALARA in Aviation What is Reasonably achievable space weather SIGMET
significant meteorological phenomena
a format pilots are used to
typical levels (moderate, severe, extreme) can be set according to DOT/FAA/AM-16/5
a good first step in the right direction

10. ALARA in Aviation 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 questionable
VC started informing their members about solar activity via in 2012
since 2016 more ALPAs join in

11. ALARA in Aviation WHAT IS REASONABLY ACHIEVABLE
information on solar activity at dispatch
education of flight crews
education of dispatchers
commander is responsible for health and wellbeing of crew and passengers
needs solid information to base their decisions on

12. LEt’s Get started!
Thank you very much.
