Measurements of activities of gamma and X-ray emitters
collected in the frame of two major projects: Off-Site Monitoring of
Krsko Nuclear Power Plant, and Survey of Radioactivity in the
Environment in Republic of Slovenia
surveys of radioactivity from different sources (industrial objects, mines,
hospitals, coal- fired power plants...),
inspection of food and other materials during import or
export of goods etc.
Laboratory measurements of activities in samples:
In-situ measurements of gamma-ray emitters in the environment.
Measurements in emergency conditions in case of nuclear or
radiological emergencies.
We perform about 1000 measurements (10000 determinations) per year.
high-resolution gamma-ray detectors with the analogue electronic
pulse-processing equipment and AD converters,
computers and software,
passive and active shields,
spectrometers for in-situ measurements,
system for detector calibration
sampling and sample preparation equipment,
software for quality assurance and control.
control measurements with calibrated point sources on each
spectrometer on a daily basis,
on-line evaluation of quality of the measuring process,
regular participation in international intercomparison runs from the year 1985.
Research and development of measurement and analysis methods
Continuos improvements of measurements and analyses:
calculation of activities of inhomogeneous samples,
calculation of activities of X-ray emitters,
calculation of activities of radionuclei with summing-coincidence
corrections,
activity calculation from in-situ measured spectra,
development of active shields.
We are regularly participating at international conferences
We publish the results of our research in main international journals.
Some of our important articles are:
We are regulary participating in international intercomparison measurements
of samples, organized by International Atomic Energy Agency IAEA,
National Physical Laboratory (NPL) from United Kingdom,
Institut de radiopysique appliquée (IRA) from Switzerland
and World Health Organisation WHO.
We participate in Workshops on Mobile Radiological Laboratories
(mainly intercomparison of in-situ measurements), which are organized
on yearly basis by one of European countries (in the year 1996 the
Workshop was
organized by our Laboratory.
We cooperate in characterization of Certified Reference Materials:
IAEA, NPL, National Institute of Standards and Technology (NIST)
from USA.
We are a member of the ALMERA network - a group of laboratories
which support agency IAEA at the measurements of activities and at
development of methods of activity measurements.
We analyse samples within large international projects IAEA like
environmental assessment missions in Kazakhstan and Kyrghyzstan.
We collaborate as advisers and experts in programs of
technical assistance of IAEA to its member states.
We participate in international projects EUROMET (Transfer
of Ge Detector efficiency calibration from point source to other
geometries) and IAEA (Calculation of detector
responses to gamma-rays from extended sources).
We offer creative working environment to perform graduate,
post-graduate and Ph.D. thesis.
In the framework of IAEA programs we offer possibilities for education
of experts from developing counties.
We organize workshops in the field of gamma-ray spectrometry.
