NATURAL RADIONUCLIDES IN AGRICULTURAL PLANTS FROM NORTHERN THAILAND.

abstract：:Calcium fluoride CaF2 is an interesting host lattice for rare earth (RE) activators. CaF2 crystals doped with different concentrations of Dy, Ce, Er and Gd have been grown by the Bridgman technique and their deformation luminescence (DL) induced by room temperature gamma irradiation has been recorded. When a uniaxial ...
