Magnetic field risk assessment
The growing spread of electronic devices, wireless networks and telecommunications systems has made the magnetic field risk assessment an indispensable activity for public bodies, companies and private individuals. Electromagnetic fields are in fact increasingly pervasive in our environments, both due to natural sources (such as the Earth’s magnetic field or lightning) and to the presence of artificial sources such as radio-TV antennas, electrical systems, household appliances, mobile phone repeaters and urban technological infrastructure.
To ensure compliance with the limits set by regulations and to protect public health and the environment, an in-depth technical analysis is necessary. For this very reason, S.T.A. offers a specialist magnetic field risk assessment service, combining technical-scientific expertise, certified instruments and full compliance with current legislation.
What magnetic field risk assessment is
The assessment of the risk associated with magnetic fields is a technical activity involving the measurement and analysis of the electromagnetic waves generated by various sources present in a given environment. The aim is to determine whether exposure levels exceed the limits set by law and, if so, to propose the necessary corrective actions.
Magnetic fields are divided into:
Low-frequency fields, typical of power lines, transformers and industrial machinery
High-frequency fields, generated mainly by telecommunications systems and wireless devices
The main risk associated with these waves is biological in nature, linked to the heating of exposed tissues. Although current studies do not confirm with certainty a correlation between exposure and the onset of serious diseases, caution and prevention remain essential to protect the most exposed people, such as workers and populations living near technological infrastructure.
Reference regulations
In Italy, regulation of exposure to magnetic fields is based on an articulated regulatory framework that includes national laws, European directives and recognised technical standards. Legislative Decree 81/2008 classifies electromagnetic fields as physical agents and requires their assessment within the Risk Assessment Document (DVR), making it an obligation for all employers. This is complemented by Framework Law no. 36/2001, which sets out the general principles for the protection of health from electric, magnetic and electromagnetic fields. Further provisions are provided by Legislative Decree 194/2007, which transposes Directive 2004/40/EC, and by the CEI and UNI technical standards and the recommendations of the ICNIRP (International Commission on Non-Ionizing Radiation Protection). All these sources set the maximum exposure limits for both workers and the general population and specify how measurements are to be carried out. Therefore, the magnetic field risk assessment is a fundamental tool to ensure regulatory compliance, but above all to protect the health of people potentially exposed in work and residential settings.
The services offered by S.T.A. for magnetic field risk assessment
- preliminary analysis of the area and the sources present
- broadband and narrowband instrumental measurements
- high- and low-frequency surveys
- study of the environmental impact of electromagnetic emissions
- drafting of the Municipal Telecommunications Plan
- mapping of sensitive sites (schools, hospitals, residential areas)
- technical support in drafting TLC system plans
- preparation of the preliminary report for the V.A.S. (strategic environmental assessment) screening
- drafting of the technical and training report in compliance with regulations
Every project is tailor-made, carefully considering the characteristics of the environment and the Client’s needs. In addition, we accompany every phase of the process with continuous assistance, including during approval and dealings with the supervisory bodies.
Who the service is for
Our magnetic field risk assessment service is designed for:
- Municipalities and local authorities, which need to plan the distribution of telecommunications facilities across their territory correctly
- Industrial and commercial companies, which use electrical systems or high-frequency devices
- Healthcare and educational facilities, for the protection of sensitive individuals
- Professionals and technical firms, for support in designing new systems or updating technical documentation
The service is also suited to environmental monitoring, urban development plans and assessments related to changes to existing technological systems.
The benefits of magnetic field risk assessment
Carrying out an accurate assessment of magnetic fields brings numerous benefits, both from the regulatory standpoint and in terms of environmental sustainability and health protection.
Among the main benefits:
- reduced risks for workers and citizens
- prevention of disputes and administrative penalties
- compliance with all applicable legal provisions
- improved transparency towards the population
- informed management of existing and future technological systems
Another aspect not to be underestimated is reputational value: a public body or company that invests in magnetic field risk assessment demonstrates concrete attention to public health and the environment, improving the trust of citizens and stakeholders.
When to carry out the assessment
- when planning new telecommunications systems
- before installing devices with high electromagnetic intensity
- when drafting or updating the DVR
- when environmental issues or disturbances reported by residents are detected
- during urban reorganisation operations
Periodic checks are always advisable, especially in areas with a high density of installations or close to sensitive facilities. In these contexts, even small changes in the configuration of the systems can significantly alter exposure.
