PURPOSE:To prevent the adhesion of a sticky material to a sampler, by inclining the inner peripheral surface of the blade part provided to the leading end of a cylindrical sampler main body internally toward the leading end thereof and protruding a root part end of said main body so that the outer peripheral surface is externally inclined in a leading end sharpened state. CONSTITUTION:The leading end blade part 1a of a sampler main body 1 comprising a metal cylindrical body is constituted so that the inner peripheral surface is formed into a first inclined surface 2 internally inclined toward the leading end thereof and the outer peripheral surface thereof is formed into a second inclined surface 3 externally inclined toward the rood part thereof. The inclined surfaces 2, 3 are provided so as to be intersected at a sharp angle at the leading ends thereof and the inclined surface 3 is formed so as to be protruded from the outer peripheral surface of the sampler main body 1. When this sampler is pushed in a sticky material to collect a specimen to be tested, the sticky material is almost not adhered to the sampler and specimen sampling efficiency becomes well. Because no water is used at the time of collection, for example, this sampler can be used in a substance formed by solidifying radioactive waste by asphalt. |
