Radiological instrumentation

Radiological equipment is intended for operation with closed and open radiation sources to reduce the dose of irradiation of the personnel. Protection of personnel is ensured by the use of tools with protective screens or with long handles (method of protection by distance). To extract radioactive drugs (see) from containers (see Containers radioisotope) use special remote manipulation tweezers, branches which in order to avoid compromising the integrity of drugs have rubber nozzle. To capture and introduction into the fabric rudonosnykh needles used remote tweezers and havnegata with a cutout for the premises regionalnoi needle (Fig. 1). Work with radioactive beads carried out with the help of a special tool, which allows remote various manipulations - from preparation of threads and beads before introducing them into the body cavity (Fig. 2). For preparation of radioactive beta-applicators employ special scissors with protective screen of organic glass, thereby reducing the dose rate at the hands of staff. Beta-applicators store in the protective canisters made of organic glass or in standard containers (Fig. 3).
Extract ampoules and vials with radioactive substances from containers and transfer them to produce special remote tweezers or remote holders, each of which is intended for a certain type of product (Fig. 4). Opening vials with radioactive substances are produced using special platonovskaya, and the bottle fix remote release button (Fig. 6). Liquid radioactive substances poured special remote eyedropper, which is mounted on a tripod and connected by a flexible hose with a syringe dispenser (Fig. 5). Radioactive solution is injected into the tumor tissue radioprotective syringes (Fig. 7)with protective shields made of organic glass (to work with beta-emitters) or of lead (for gamma emitters).
The radiological instrumentation requires certain skills, and perform all these operations takes longer than when using normal tools. However, this should not be a reason for rejection of the use of radiological instrumentation, which helps reduce radiation exposure and makes the work of personnel almost safe. Performing manipulations with radiation sources without the use of radiological instrumentation is strictly prohibited. At receipt for work in radiology Department personnel should receive specific training on the use of radiological instrumentation initially on the simulators of radioactive compounds. Radiological instrumentation requires careful handling, careful maintenance and, if necessary, decontaminated, which is performed by washing tools for a long time in running water. Before using radiological instrumentation checked his health. Widespread receive special protective cabinets and tables, with walls built radiological instruments of various types.radiological the Toolkit
