Monitoring Radioactivity in Water Intended for Human Consumption

The presence of radioactive substances in water intended for human consumption is regulated at the national level to ensure public health protection.
With the Ministerial Decree of 2 August 2017 (Official Gazette No. 212 of 11-09-2017), the Italian Ministry of Health established guidelines for the uniform application of Legislative Decree 28/2016, defining concentration limits and analytical methodologies for monitoring radioactivity in drinking water.

Thanks to its UNI CEI EN ISO/IEC 17025-accredited laboratories, LB Servizi provides sampling, analysis, and certification services to ensure compliance with regulations and the safety of water intended for human use.

Radioactivity Control in Water

Monitoring activities are conducted in accordance with the control plans prepared by the responsible authorities.
The main analyses include:

Determination of Radon-222 (²²²Rn) and Tritium (³H) concentrations
Measurement of the indicative dose through total alpha and beta activity

Advanced Analyses in Case of Anomalies

When anomalies are detected or upon specific request, more in-depth investigations are carried out on specific radionuclides, including:

Strontium-90 (⁹⁰Sr)
Radium-226 (²²⁶Ra)
Uranium-234 (²³⁴U), Uranium-235 (²³⁵U), Uranium-238 (²³⁸U)
Polonium-210 (²¹⁰Po)
Plutonium-238 (²³⁸Pu) and Plutonium-239/240 (²³⁹/²⁴⁰Pu)

These analyses are essential to ensure compliance with safety parameters established by current legislation.

Compliance Obligations for Water Network Operators and Companies

The regulation requires the monitoring of drinking water distribution networks by:

Aqueduct and water utility operators
Food and paper industries
Bottling plants for mineral water

Controls may be carried out directly by service providers or by external accredited laboratories.
Any laboratory performing analyses must be ACCREDIA-accredited in accordance with UNI CEI EN ISO/IEC 17025.

As an accredited laboratory, LB Servizi guarantees reliable, precise, and regulation-compliant analyses.

Advanced Analysis Technologies and Instrumentation

LB Servizi uses state-of-the-art equipment to ensure maximum precision in water radioactivity analyses. Key technologies include:

Ultra-low background detection system with TDCR (Triple-to-Double Coincidence Ratio) technology, which minimizes environmental background signals and enables detection of extremely low activities.
Online platform for consulting results and downloading test reports.
