<p>PROBLEM TO BE SOLVED: To provide a light weight shield plate for radiation ray which is light weight, easily portable and easily wearable.SOLUTION: Light weight of a shield structure of radiation ray can be achieved and reduction and shielding effect of the radiation ray can be obtained by processing material to a shape which can be expected by refraction effect of the radiation ray with material having the reduction and absorption effect of the radiation ray. Increase of the reduction and shielding effect can be expected by laminating a reduction and shielding plate.</p> |
