  • Title: EPR signal enhancement of alanine irradiated with thermal neutrons.
    Author: Galindo S, Ureña-Nuñez F.
    Journal: Radiat Res; 1993 Mar; 133(3):387-9. PubMed ID: 8383863.
    Abstract:
    A method to enhance the electron paramagnetic resonance signal amplitude response of alanine to thermal neutrons is presented. The method is based on the production of additional free radicals caused by alpha-particle and 7Li interactions on the alanine. These particles emerge from the neutron capture 10(5)B (n, alpha) 7(3)Li reaction. For this purpose, alanine and boric acid are intimately mixed. Mixture intimacy is critical for optimum enhancement. A way to achieve good mixture intimacy is suggested. A signal enhancement up to 2200% is obtained.
