Available natural radioactivity (⁴⁰K, ²³⁸U,
²³²Th) measurements on Plio-Quaternary volcanic
and pyroclastic rocks, which are usually used to as building raw materials,
from the Isparta region of SW Turkey, released that their radium equivalent
activity values are close to the internationally accepted upper limits and a
potential radiation risk. Here, to deciphere the what caused the high radiation
values in these volcanic materials carrying value by more than three times the
equivalent materials in Turkey, the relationship between their magma and source
characteristics has been investigated. Recent volcanological studies have shown
that potassic-ultrapotassic magmas governed the genesis of the Isparta
volcanism. K-rich character’s and elevated concentrations of radiogenic (e.g.,Th
and U) and total rare earth elements (∑REE) are their most diagnostic features.
These characteristics are also similar to some mantle-derived carbonatites  (e.g., Norwage and Kenya) with high radiation
levels. To support this, recent investigations also revealed that the origin of
Isparta potassic volcanism is associated with a common and enriched mantle
source, which were interacted with carbonatite melts. Accordingly, carbonatitic
melts left their geochemical imprints into their mantle sources, and partial
melting of this mantle source produced K, REE, Th, and U-rich volcanic
materials with high radiation levels in the region. These results indicate that
the carbonatite-influenced mantle source were played a key role for not only
enrichments in distinct (e.g., Th, U and REE) elements but also high
radioactivity levels in Isparta volcanic and pyroclastic rocks. Here, attention
is drawn to the fact that a potential risk of high radiation in volcanic and
pyroclastic rocks used as building raw materials can be expected for a given
volcanic region, which include potassic magma derived from a carbonatite-modified
mantle source.
