In INTERNATIONAL ROUTES
of Argentine Airlines
Aircrew Members Flew more than 700 hs per year
accumulating between 2 and 7 MilliSievert year.
This Dose exceeded the ICPR Recommendation that limit for
the General Population in 1 mSv/y.
Because Argentina did not have yet Regulations
for Aircrew members this maximum level must
be considered for them.
• ICRP recommendations for
• Aircrews of jet aircraft:
– 5-year mean effective dose of 20 m Sv per year,
– with no more than 50 mSv in a single year
– After pregnancy reported: equivalent dose to
conceptus should not exceed 1 mSv
• General Population :1mSv per year.
– FAA recommendations Pregnancy: equivalent dose to
conceptus should not exceed 0.5 mSv in any month

The extreme solar cosmic ray particle event on 20 Jan. 2005
and its influence on the radiation dose rate at aircraft altitude

ABSTRACT
In January 2005 toward the end of solar activity cycle 23 the Sun was very active. Between
15and 20 January 2005, the solar active region NOAA AR 10720 produced five powerful solar
flares. In association with this major solar activity several pronounced variations in the
ground-level cosmic ray intensity were observed. The fifth of these flares (X7.1) produced
energetic solar cosmic rays that caused a giant increase in the count rates of the groundbased
cosmic ray detectors.. At southern polar neutron monitor stationsthe increase of the count
rate reached several thousand percent. In the initial phase of the event the solar cosmic ray
flux near Earth was extremely anisotropic. The energy spectrum of the solar cosmic rays
was fairly soft during the main and the decay phase. We investigated also the flux of different
Secondary particle species in the atmosphere and the radiation dosage at flight altitude.
Our analysis shows a maximum increment of the Effective Dose Rate due to solar cosmic
rays in the South Polar Region around 70°S and 130°E at flight altitude of almost
THREE orders of magnitude.

Aims: To investigate whether length of employment as a cabin attendant was related to breast cancer risk,
when adjusted for reproductive factors.
Methods: Age matched case-control study nested in a cohort of cabin attendants. The cases were found
from a nationwide cancer registry (followed up to end of year 2000) and the reproductive factors (age at
first childbirth and number of children) from a registry of childbirth, in both instances by record linkage
with the cabin attendants’ identification numbers. The employment time of the cabin attendants at the
airline companies and the reproductive factors had been systematically recorded prior to the diagnosis of
breast cancer in the cohort. A total of 35 breast cancer cases and 140 age matched controls selected from
a cohort of 1532 female cabin attendants were included in the study.
Results: The matched odds ratio from conditional logistic regression of breast cancer risk among cases and
controls of cabin attendants was 5.24 (95% CI 1.58 to 17.38) for those who had five or more years of
employment before 1971 compared with those with less than five years of employment before 1971,
adjusted for age at first childbirth and length of employment from 1971 or later.
Conclusions: The association between length of employment and risk of breast cancer, adjusted for
reproductive factors, indicates that occupational factors may be an important cause of breast cancer
among cabin attendants; the association is com

As SPECIALISTS in AEROSPACE MEDICINE WE HAVE a SPECIFIC
MEDICAL RESPONSIBILITY (Personal, Professional, Legal and Moral)
in this new FIELD of the WORLD COMMERCIAL AVIATION.
In Argentine we presented a PROJET of LAW to IMPLEMENT two
principal issues related with RADIOVIGILANCE and
RADIOPROTECTION.

Background.
With the advance of the aviation science and technology, the new commercial jet aircrafts fly higher,
more rapidly, and make more distant non-stop, ultra long-haul flights. For these reasons,
aircrew members are flying more intercontinental routes, which has made them the
second most occupationally exposed population to Cosmic Radiation Dose (CDR) levels,
exceeding the current limits recommended by ICRP in Vienna, Austria of 1mSv/year.
Because astronauts are the most occupationally exposed group to ionizing radiation
a top priority was to reduce the total levels of radiation exposure in earth orbit of ISS.
High Density PolyEthylene (HDPE) was used by NASA and installed in the temporary
sleep station onboard the US Laboratory Module of the ISS.
This has resulted a significant reduction (20- 40%) of the
radiation dose levels received by the crewmembers when they occupy the sleep station.
The aim of the present study was to assess this new material applied, in this case,
on-board commercial jet aircraft, to evaluate the possible reduction of CRD levels,
as is inherent in the “ALARA PRINCIPLE” from standard Radioprotection practice.
