REFERENCE SURFACE FOR IN SITU GAMMA SPECTROMETRY.

Chemical laboratories of the Fire Rescue Service of the Czech Republic are part of the radiation monitoring network and participate in the radiation situation monitoring in the Czech Republic. Measurements in situ are crucial for monitoring the radiation situation in emergencies associated with the deposition of radioactive substances on a large area. Those data can be used for estimating a possible dose obtained either by staying in a contaminated area or by consumption of food produced in the area.

SELECTION OF SUITABLE SAMPLING TOOL FOR RELIABLE SOIL SAMPLING NOT ONLY AFTER RADIOLOGICAL ACCIDENT.

The objective of this research was to develop a sampling protocol for contaminated soils after a large radiological accident. One of the criteria for good sampling method is reproducibility and accuracy of large number of samples collected in short time. Members of the chemical laboratories of the Fire Rescue Service of the Czech Republic (FRS CR), which are included in Radiation Monitoring Network, tested four tools in different soil types.
