FEASIBILITY OF NEUTRON ACTIVATION ANALYSIS ON PAPER.

Abstract

Thermal neutron activation and gamma-ray spectroscopy were used to detect and measure trace elements in alpha-cellulose and ash-free filter paper samples. Each sample was irradiated in a neutron flux of 5 x 10 to the 12th power n/cm sq/sec for periods of 10 and 30 minutes. The activated samples were analyzed by a 3 inch x 3 inch NaI(Tl) detector crystal and a 400 channel analyzer. The trace elements found were Cl, Mn, Fe, Mg, Si, Ca, Na, and Cu. Quantitative analysis was limited because of interfering photopeaks. Experimental deviations ranged from 2.08% to 21.8% for Na, Al, Cl, Mn, and Cu to above 30% for the other elements.
