| Summary of
WSC attendance to the ICRP Task Group 74 meeting, Munich, 30
June - 2 July 2008 |
| |
| At its
meeting in Berlin last October, the International Commission
on Radiological Protection (ICRP) approved the establishment
of a Task Group No. 74 on More Realistic Dosimetry for
Non-Human Species. This task group is aimed at further
developing dosimetric models for the calculation of radiation
dose for the purpose of consolidating the international
system of protection of the environment from non-ionising
radiation. It addresses current status and remaining questions
on the ICRP dosimetry for flora and fauna, as established
by the previous Task Group 69, which helped to establish
the ICRP methodology. The task group is composed of one
representative each from the France, Germany, Norway,
Spain, UK and the USA. |
| |
| Dr. Jordi
Vives i Batlle (also involved in the Task Group 69) was
invited to serve as the UK Corresponding Member of the
new Task Group, attending the meeting at the German Research
Center for Environmental Health, Helmholtz Zentrum, Munich,
in order to participate in the Commission’s work.
|
| |
| Dr Vives’
main contribution to the meeting was an improved dosimetric
method for calculating radon exposure in animal and plant
species. The work, which stems from a recently completed
contract with the England and Wales Environment Agency,
is of particular importance because the ICRP has identified
that a critical pathway for doses to biota is inhalation
of radon, particularly for animals in burrows. |
| |
| A key
outcome of the meeting was a newly established collaboration
between WSC and the Institute of Radiation Protection
(Munich) in order to model in more detail plant respiration
for radon and other trace gases. Additional work is planned
to develop allometric modelling of animal and plant physiology
for the purposes of dose calculation. |
| |
| We thank
the NDA for generously awarding funding for attendance
to this meeting, which is a major opportunity for Westlakes
to bring back knowledge and expertise on environmental
protection that can be passed on to stakeholders in our
area. |
