Neutron Activation Analysis
Instrumental Neutron Activation Analysis (INAA) laboratory is located at AMD, HQ, Hyderabad. It is a nondestructive nuclear technique, employed to find the elemental concentrations of Na, K, Ca, Sc, Cr, Fe, Co, Zn, Ga, As, Br, Rb, Ag, Sb, Cs, Ba, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Tm, Ho, Yb, Lu, Hf, Ta, W, Au, Th and U. Measurements from percentage to ultra trace levels are possible by this technique. High purity germanium co-axial solid-state detector coupled to PC-based multichannel analyser is employed for spectrum analysis after irradiating the samples in DHRUVA reactor of BARC, Mumbai.
Radon Measurement
Radon measurement in water, soil and ambient air is being carried out in the RSA Laboratory. This laboratory has optimised the use of radon measurement in uranium exploration and environmental studies for generation of base line data.
