XI-MER 2013 XIOS-ISIB Measurements of
Environmental Radioactivity
XIOS Diepenbeek Wouter Schroeyers, Luc Lievens,
Steven Lelie ISIB Brussels Caroline Licour,
Jonathan Baré, Isabelle Gerardy
Ten-day course, 4 ECTS credits
2

• Goal
• To confront the students with possible problems
  regarding radioactivity in our environment
• ? Radioactivity measurements of artificial and
  natural contamination
• Better knowledge of the measurement techniques
• Better understanding of our radioactive
  environment
• Better evaluation of what is harmful and what has
  to be accepted.
• Participants
• Third year bachelorstudents of XIOS
• First year masterstudents of ISIB
• Individual students from Cherne partners
• Organisation

Field trip in Mol
Location Banks of the Molse Nete Discharge point
of a sewer coming from the nuclear complex
Mol-Dessel. On May the 22th of 2007,
Greenpeace published a report of one of their
actions

Field trip in Villers la Ville Weather cold and
snowy.

Spectrometry on the field
214Bi, 609keV
137Cs, 662keV
40K, 1461keV
11
Measurement of the permeability of the soil
Not possible due to the frozen soil. Permeability
very low and then, sampling of the soil air
not significant (radon in the soil air not
measured).
