Radioactive sample holder
First Claim
1. A radioactive sample holder for holding a syringe containing a radioactive sample therein, the radioactive sample holder being adapted to be loaded into a radioactivity measuring apparatus for measuring an amount of radioactivity of the radioactive sample, comprising:
- a radiation shield plate;
a shaft extending vertically downwardly from said radiation shield plate; and
a retainer disposed on a lower end portion of said shaft, for vertically retaining said syringe;
said retainer having a first support for supporting a lower surface of a flange of a cylinder of said syringe, a second support disposed above said first support at a spaced interval therefrom, for supporting an upper surface of said flange, and a groove defined in said first support and said second support, for inserting a piston of said syringe horizontally therein.

Abstract
After a syringe containing a radioactive sample therein and housed in a radiation shield case is mounted on a radioactive sample holder and set in a radioactive sample measuring apparatus, an upwardly projecting handle of the radioactive sample holder is depressed to cause a syringe holder base supported on second shafts to lower a flange of the syringe held by the syringe holder base, pulling the syringe out of the radiation shield case. Then, the amount of radioactivity of the radioactive sample contained in the syringe is measured.
