Inch – length of a thumb
Foot – length of a foot
Cubit – length of a forearm
Yard – used to sell fabric
Fathom – nautical term for depth
Rod – used for surveys
Furlong – throw of a javelin
Mile – distances on land between towns
Nautical Mile – distances on sea
League – distance on roads (different in France and
England, and period of history)
Definition of dosimetry
• What are we trying to measure?
– Goal is to evaluate the risk from exposure to
radiation
• Why so many quantities?
– Effective dose E
– Ambient dose equivalent H*

The requirement
• Aircrew are exposed to as much or more
radiation as the average nuclear worker
• International guidance recommends
aircrew track exposure
• Many countries have regulated this
tracking
• Canada has issued a notice, with
legislation in process
PCAIRE
• Developed specifically to address this
issue
• Only code based on flight measurements
• Personal dosimeters or instruments too
complex to use for routine dosimetry
PCAIRE is:
• A mathematical model based on
fine-grid measurements of
radiation at various locations
around the world.
• The largest experimental
database
• A software program that uses this
model to calculate doses

PCAIRE Sys is:
• A commercial tool designed for an
operational environment, NOT FOR
RESEARCH
• Monitoring system for large number of
personnel and flights
PCAIRE Sys
• PCAIRE Sys can operate:
– Via web - for individual users
– As a kernel incorporated into the airline’s
human resources system
– As a data treatment centre, web/LAN-based,
for processing batch files and interface with
the airline’s database
PCAIRE Sys architecture
• One calculational dll
– Compiled and secured
• Secure database access only
– For storage and retrieval of required data
– Using Microsoft’s newest security design
• Output files labeled with dll version
– All input and output data is rigorously verified
by the code

PCAIRE Sys functionality
• Single flight entry or batch file processing
• Great circle route or way points
• Database of personnel by employment
category
• Secure access
PCAIRE Sys functionality
• Runs as local application or fully webor WAN-based
• Can be interfaced with larger human
resources and flight database
• Individual crew members can query
data
– If allowed
• Administrator can query by flight, crew
or dates (period, current year, current
quarter)

PCAIRE Inc.
• An Ottawa based company
• PCAIRE is run on servers at the Ottawa
office
– Many individuals use this service to track
annual dose
– Many are US and European based aircrew
• Current airline clients are worldwide

Certification
• PCAire has been certified by the Airline regulator
in Germany – LBA
– Completed in June 2004
– Nine month certification process
• This certification is recognized by all EU
countries
• PCAire has conducted detailed data collection
and R&D and will propose an updated version
for re-certification:
– New H*10 to E conversion
– New proton/neutron weighting factors
