Development of protective device for radio isotope injection

Objective To develop a protective device for radio isotope injection based on related radiation protection principle. Methods The technical designs were carried out for tungsten alloy tube body, axial through hole, transparent lead glass bar, retaining unit, elongated boss, support springs, card board and etc. Results The device with easy operation could provide completely sealed protection. Conclusion The protective device with easy operation and high convenience can make the isotope always sealed, and can reduce the radiation to the staffs, especially to their hands, which is worth popularizing practically.
