The present invention relates to a transport container for transporting a liquid radioisotope, and more particularly, an absorbent material is provided in the shielding container, and a shielding material made of lead material is used for the I-123, I-131, and Ga-67. , The safety radioactive isotopes are leaked to the outside of the container when leaking liquid radioisotopes, such as TI-201, and a number of shielded containers are loaded to increase the transport efficiency. A type A transport container for transporting a liquid radioisotope that may be used.

In general, radioisotopes have been used to perform many researches and experiments in various fields such as medical division, non-destructive testing, and agriculture, which perform diagnosis and treatment using radiopharmaceuticals.

These radioactive materials, radioisotopes, must be transported safely from the production site to the consumer site, and require transport containers with adequate shielding to prevent exposure of the user to radiation.

Here, the transport container for transporting radioisotopes is the Ministry of Science and Technology Notice 2001-23 and IAEA Safety Standard Series No. The conditions specified in TS-R-1 and US 10 CFR Part 71 shall be met.

On the other hand, radioisotopes used for medical purposes are manufactured and used in the form of liquids or capsules, and radioisotopes such as I-123, I-131, Ga-67, and TI-201 used for medical purposes are relatively used. It is manufactured in liquid form with a capacity of 20mCi to 50mCi of the weak radiation intensity, and the radiation intensity is transported using a type A container.

Domestic and foreign legislation requires that type A containers for transporting liquid radioisotopes should have two containment boundaries or one containment boundary containing absorbent material if the radioisotope stored in the container is a liquid.

Here, the absorbent material of the type A container must be capable of absorbing twice the amount of the liquid radioisotope stored in the type A container, and in case of a drop accident at a height of 9 m in preparation for a safety accident that may occur during transport. The importance of safety in transport containers for transporting radioactive isotopes is being stipulated, for safety reasons.

1 is an exploded perspective view showing a type A transport container carrying a liquid radioisotope according to the prior art.

As shown in the figure, the A-type transport container 100 conventionally used for the transport of a liquid radioisotope is a glass container (110, Vial) formed of a small glass material and a shielding container made of lead material 130, the shock buffer is made of a styrofoam material and is composed of a cylindrical container-shaped transport container (150, Over-pack).

The A-type container 100 having the structure and configuration as described above contains a liquid radioisotope in the glass bottle 110 to primarily store the liquid radioisotope, and the glass bottle 110 is made of lead. After the shielding container 130 is placed, the shielding container 130 is loaded in the transport container 150, and then the lid of the transport container 150 is closed, and the liquid radioisotope is transported after the taping operation.

Since the Type A container does not use a liquid absorbent material therein, the shielding container or the transport container should perform a secondary containment boundary to prevent leakage of the liquid radioisotope to the outside of the transport container. There is no configuration for containment in the container, and the taping operation for treating the container is difficult to carry out the storage, and thus there is a problem that it is difficult to completely prevent the liquid radioisotope from leaking out of the container from the occurrence of a transport accident.

On the other hand, the A-type transport container 200 used in the prior art for the transport of the liquid radioisotope as shown in Figures 2 and 3 is a shield made of glass and glass (210, Vial) and lead material of the glass material The shock absorber is made of a container 230 and a sponge-based, and is formed in a shape similar to approximately a barrel barrel, it is composed of a transport container 250, Over-pack to install a plurality of shielded containers therein.

The A-type container 200 having the structure and configuration as described above contains a liquid radioisotope in the glass bottle 210 to primarily store the liquid radioisotope, and the glass bottle 210 is made of lead material. After putting in the shield container 230, the cover is closed to the shield container (230).

Then, a plurality of the shield container 230 is loaded in the transport container 250, and the lid of the transport container 250 is closed to secondary containment, and then the liquid radioisotope is transported.

However, the A-type transport container as described above is provided with a cushioning member of rubber material on the inner surface of the lid of the transport container, but because there is no configuration for the storage of a plurality of shielding containers installed therein transport accident It is difficult to completely prevent the liquid radioisotope from leaking out of the container when it is damaged.

In addition, there is a problem that a safety problem is caused because no configuration for storage is made like the A-type container shown in FIG. 1.

In addition, the A-type transport container as described above is a situation that is used or discarded after being used once by the shielding container made of lead material. This is because it is difficult to decontaminate lead contaminated from radioactive material, which has a problem that the environmental pollution is increased due to the continuous production and continuous disposal of the shielding container for the transport of liquid radioisotopes, and the cost is increased.

On the other hand, in the consumption of radioisotopes, generally two to three radioisotopes of 20mCi to 50mCi are required, so that a cylindrical shaped container containing one lead shielding container is transported from the production site to the consumer. 2 ~ 3 transport containers are transported at a time and 8 ~ 10 shield containers are loaded at the same time. As a result, there was a problem of lowering the efficiency of transportation.

The present invention is to solve the problems as described above, the present invention is to provide a shielding container with an absorbent material is installed in the liquid radioisotope such as I-123, I-131, Ga-67, TI-201 used for medical purposes Prevents safety accidents such as liquid radioisotopes leaking and leaking out of the container during transportation, and can be reused repeatedly by applying a shielded container made of lead and stainless steel. To provide a Type A transport container for transporting liquid radioisotopes that not only reduce costs, but also cause environmental pollution and can be carried by a plurality of shielded containers, thereby increasing transport efficiency. do.
