- •
Distribution of natural radionuclides in an U-rich aplite from Central Portugal.
- •
INAA, XRD and gamma spectrometry were applied to various types of samples.
- •
Higher U values for clay/sand fractions, and core of spheroidal weathered aplite.
- •
225">Large difference between pre-Rn and post-Rn values suggests high loss of radon.
- •
Weathering of aplite is a potential source of radiological hazards.
