Abstract

The 238U, 226Ra, 210Pb, 228Ra, 228Th and 40K concentrations have been measured beside to radon emanation factor due to sample granulometric using γ-spectrometry. The radiological hazards of zeolitic rocks application in the environment as soil improvements, diet supplements and building materials have been studied. No γ-radiation hazards occur for soil improvements since up to 0.13 mSv year−1 estimate. No radiation hazards arise for diet supplements since 0.21 μSv day−1 g−1 of zeolite intake is estimated. Instead, the application as cement and bricks give external annual effective dose up to 1.19 mSv, while the internal radiation rises to 3.45 mSv.
