In her role as an Assoradon member, she actively promotes the culture of prevention against environmental radioactive risks. In June 2025, she actively participated in the national conference IRSOIL 2025, presenting to the scientific audience a targeted and complex study characterizing dissolved radon concentrations in water within mining work environments.

Frequently Asked Questions

Everything you need to know about qualified professionals in the Radon field and current Italian regulations.

Who is the Radon Remediation Expert?
It is a professional (surveyor, engineer, or architect) registered with their respective professional board who has obtained a specific qualification through a university course of at least 60 hours, as required by Art. 15 of Italian Legislative Decree 101/2020. Only this figure possesses the credentials to design certified remediation systems.
Who is the Qualified Expert in Radiation Protection?
The Radiation Protection Expert is a highly specialized technical figure, listed in a specific national register at the Ministry of Labor, legally authorized to sign the technical radiometric reports of radon gas measurements.
Why is it mandatory to rely on certified professionals?
Radon gas is an invisible carcinogen that is lethal over the long term. Decree 101/2020 imposes severe penalties for non-compliance in workplaces. If the measurement or remediation project is not signed by formally authorized figures, the intervention is considered null and void in the event of an inspection.
Can any engineer or surveyor design a radon remediation?
No. Only registered civil professionals who have passed the exam for the specific 60-hour university training course acquire the formal title to draft projects, coordinate site work, and swear the testing of mitigation systems.
What is Assoradon and why is membership important?
Assoradon is the National Association of Radiation Protection and Radon Remediation Experts in Italy. Belonging to this body guarantees continuous scientific-technical updating by its members and compliance with strict operational and ethical quality standards in the field.
Can I use DIY electronic meters to measure radon myself?
Low-cost commercial detectors available on the market are useful for informal domestic screening, but their data have no legal value. To comply with regulations in workplaces or leased properties, a report must be drafted using traceable dosimeters analyzed in ISO laboratories.
Do your technicians operate throughout Italy?
Yes, we handle active and passive measurement procedures throughout the national territory via tracked courier shipments, and we follow architectural design sites for Radon mitigation via direct on-site inspections in any region where there is urgency and need.
What is the next step if I find radon levels above the norm in my home?
You must promptly contact a Remediation Interventions Expert, such as our Geologist Andrea Gritti. The expert will proceed with in-depth diagnostic investigations on the geology of the soil and the structure of the building to then design a tailor-made ventilation solution, monitoring its progress until the successful remediation is certified.
Are there penalties for skipping measurements in the work environment?
Absolutely yes, in all work environments that are predominantly underground, semi-underground, on the ground floor, in thermal centers, or in geographical areas mapped as at risk, the employer risks an arrest of one to six months or very heavy financial penalties and the closure of the premises.
Do you offer specialized support during new construction projects?
Certainly. Preventing radon during construction costs up to 80% less than post-operam remediation. Our professionals support and collaborate with third-party engineers and architects to propose special stratigraphies and waterproof foundations against the transit of underground fluids (for example via an aerated crawl space).
