The detection of radioactive elements in the environment is carried out in specialised laboratories equipped with the necessary apparatus, such as the Department of Environmental Radioactivity Monitoring at the EEAE.
The choice of analytical method is determined by the type of sample and the radioactive element we are seeking to detect.
The laboratory measurements carried out by the EEAE as part of its service provision relate to:
- samples of soil, water, food, air filters, etc., using alpha and gamma spectroscopic analysis and total alpha/beta radiation measurement,
- radiological testing of drinking water and water samples from reservoirs, lakes and boreholes to detect radioisotopes,
- foodstuffs intended for export or for sale in Greece,
- imported materials and products,
- building materials and materials intended for the industrial production of building materials,
- materials with elevated levels of natural radioactivity (Naturally Occurring Radioactive Material, NORM),
- areas with elevated levels of natural radiation (phosphogypsum disposal sites, areas with elevated levels of radon in the indoor air of dwellings),
- objects/materials with elevated radioactivity identified during the inspection of scrap metal.
The results of all radioactivity measurements carried out in the country are stored in the National Radiation Protection Database maintained by the EEAE.
The charges for sample analyses are set out in point (b) of paragraph A of the list of charges for services provided by the EEAE (you can view here the table of charges).
Measurement methods
Various methods are used for the radiological analysis of samples, such as gamma spectroscopy in low-background setups, alpha spectroscopy, the total alpha/beta radiation measurement method, and the measurement of alpha and beta radiation using a liquid scintillator.
MOREAnalysis of drinking water samples
The EEAE carries out systematic analyses of drinking water samples for tritium and the indicative dose (uranium isotopes U-238, U-234 and total alpha and beta radiation), in accordance with Directive 2013/51/Euratom laying down requirements for the protection of the health of the general public with regard to radioactive substances in water intended for human consumption.
MOREOn-site measurements – surveys
Monitoring environmental radioactivity usually requires on-site inspections. The EEAE carries out sampling of soil, water and air samples using a fully equipped mobile laboratory, as well as portable detectors to measure radiation dose and surface contamination.
MOREShipments of old iron ore
Measures are being taken in our country to ensure the protection of workers, the general public and the environment from potential radiological contamination in scrap metal (scrap).
MOREDetection system findings in steelworks
Fixed detection systems (portals) are installed at steelworks and are used to screen goods and consignments of scrap metal for radioactivity. The EEAE is immediately notified of any alarms and, where necessary, carries out on-site inspections and provides guidance on how to manage any radiological findings.
