Shielding and Resistant Properties of Radiation─Proof Methacrylate Sheets

Zhang Xingxiang;Wang Xuechen;Niu Jianjin ;Chen Changmao;(Tianjin Institute of Textile Science and Technology) (Sinia Institue of Atomic Energy)  
The radiation resistant properties of Pb--,Ba--,and B-containing methacrylate sheets andordinary sheet against X-- ray, T -- ray neutron shielding and 6oCoY-- ray of different energyare studied. The results show that the Pb--containing methacrylate sheets are excellent for X-ray and reactor r--ray shielding, the B--containing sheet is effective to thermal neutron shielding ;and the Ba--containing sheets are useful in shielding the fission spectrum neutron. The resistant dosage of Ba--containing and ordinary methacrylate sheets to 60CoY--ray is 105-- 106 Gy.And the resistant dosage of Pb--containing methacrylate sheets to 60COY-- ray is 105Gy.
