Public defense - Frøydis Meen Wærsted

Alum shale is an acid-producing type of rock that can be encountered in mining and construction work in Northern Europe. Such shales can have high levels of naturally occuring radioactive material (NORM) and stable trace elements ("heavy metals"). In her project, Frøydis Meen Wærsted performed leaching experiments to investigate how different storage conditions of the excavated rock would impact the mobility of NORM and stable trace elements.

Frøydis Meen Wærsted has successfully defended her PhD thesis "Mobility of naturally occurring radionuclides and stable elements in alum shale: A case study of Gran, Highway 4, Norway" September 28th 2019. the title of her trial lecture was "The role of organic material in migration and transport of radioisotopes - coupling of microbiology and radioisotopes".
