A new scientific contribution has just been published in The European Physical Journal Plus, under the Focus Point on CBRNE Events: Prevention, Mitigation, Consequences and Recovery, linked to the SICC Series CBRNe Conference 2023.
The article, titled “Luminescent sensors with differential fading for nuclear safeguards” (Regular Article, Vol. 140, Article number 874, 2025), presents an innovative approach to nuclear safeguards by testing passive tamper-indicating devices based on luminescent sensors.
The study, authored by Gianpaolo Roina, Debora Siqueira Nascimento, Riccardo Ciolini, and Francesco d’Errico, explores how differential fading of thermoluminescent signals in LiF:Mg,Cu,P crystals can be used to detect and timestamp unauthorized access or removal of nuclear materials. Results from the pilot testing demonstrated a remarkable ability to estimate the elapsed time since exposure with uncertainties of only ±1 day during the first week and ±1 week within two months.
Special congratulations go to Gianpaolo Roina, Principal Investigator of the work, for this important step forward in strengthening containment and surveillance measures in nuclear safeguards.
