On 10.06.2021, Senior Assit. Prof. PhD Elena Geleva presented a report on “Investigation of natural radioactivity in mineral water”. She presented results of a study of the natural radioactivity in mineral water from certain most frequently used sources in Bulgaria. The survey is pointed at radium-226 (Ra-226), lead-210 (Pb-210), natural uranium (nat. U), gross alpha and beta activity. Based on the radionuclide activity concentrations total annual effective ingestion doses for adults, as well as contribution of each particular radionuclide to the total doses, were assessed.
The obtained new results are used to assess the radiation status of the investigated water. They will support timely and adequate measures to reduce the harmful impact of ionizing radiation on the population in cases of increased radioactivity.
