Polonium-210

Following our tradition and aspiration for development, the laboratory constantly strives to add new methods to its accreditation. The specialists from CSRL at DIAL Ltd. developed a method for alpha-spectrometric analysis of polonium-210.
After the last audit by IA BSA, the laboratory has been successfully accredited to perform water testing for Po-210.
We are happy to provide this new analysis service to you!.

Activities are related to:

  • Analysis and assessments of the quantities and types of materials with an increased content of natural radionuclides that are used for the activity or its product;
  • Measurement of the specific activity of materials with an increased content of natural radionuclides used for the activity or obtained from it;
  • Measurement of gamma radiation dose rate at the workplaces and at a distance of 0.1m and 1.0m from the used and obtaining materials with an increased content of natural radionuclides related to the activity;
  • Assessment of the expected doses of external and internal radiation of workers and members of the population;
  • Issuance of an expert opinion on the assessment of external and internal exposure of workers and members of the public.

We already have many satisfied customers and our cooperation with them continues.

If you also need expert activity - do not hesitate to contact us! We have rich and long-term experience and highly qualified staff to meet your needs!

RADON IN RESIDENTAL BUILDINGS. The risks to human health are increasingly spoken as a result of radiation from the natural radiation background. Much of this exposure is due to radon and its daughter radionuclides. The natural radioactive element radon (radon-222) has the largest contribution to the internal radiation of the Earth's population. According to the 2008 report of the Scientific Committee for the Study of Atomic Radiation at the UN, 41% of the population's exposure is due to the inhalation of radon.

Monitoring of closed uranium mining sites in Bulgaria

By Decree of the Council of Ministers No163 of 20.08.1992 the uranium mining in Bulgaria was terminated. A very important project, under which DIAL has been working for more than 20 years, is the monitoring of the closed uranium mining sites in Bulgaria. Despite the 25 years since the end of this activity in Bulgaria, natural resources (soils, water, air) have not yet been fully restored and their monitoring is of great importance for limiting the harmful effects on human health.
