Re‐assessment of the risks to public health related to the genotoxicity of styrene present in plastic food contact materials

EFSA Journal, Volume 23, Issue 6, June 2025.
Abstract The EFSA Panel on Food Contact Materials (FCM) was requested by the European Commission to re‐evaluate the potential genotoxicity of styrene after oral exposure and its safety for use in plastic FCM with a specific migration limit (SML) of 40 μg/kg food.

Verification of the applicability of the RAD7 radon monitor to the solid radon source exhalation reference model

Nuclear Engineering and Technology
The RAD7 radon monitor, based on the electrostatic collection method, is sensitive to humidity during measurements, necessitating the use of a desiccant to maintain the relative humidity in its built-in chamber less than 10 %.

Functional Lung Imaging Identifies Peripheral Ventilation Changes in ꞵ‐ENaC Mice

Respirology, Volume 30, Issue 4, Page 335-345, April 2025.
β‐ENaC‐Tg mice have previously been shown to exhibit muco‐obstructive disease and emphysema. This study analysed lung function in β‐ENaC‐Tg mice using XV functional imaging and flexiVent assessments. XV enabled ventilation defects to be identified and localised, and the flexiVent comfirmed increased lung compliance and reduced tissue elastance ...

A study of the natural radioactivity and radon exhalation rate in some cements used in India and its radiological significance

Journal of Radiation Research and Applied Sciences, 2016
The presence of natural radioactivity and radon exhalation from building materials contribute to the radiation dose received by human. So, it is essential to evaluate the activity levels of the primordial radionuclides (238U, 226Ra, 232Th and 40K ...
