Irradiation facility for machine parts at our compact cyclotron KAZ


Radiation exposure of the user?

Radiation exposure of the user only occurs during handling - mounting the activated machine parts. It is maximum about one tenth of the limit value for the normal population (natural radiation dose of an individual of the population).
Irrespective of the low radiation dose, the radiation protection legislation demands the monitoring of the exposure dose of those people who handle activated parts.

Is a handling license for radioactive materials required?

Similar to the handling of dangerous substances like solvents (chlorinated hydrocarbons, gasoline, etc.) and waste oil - there are regulations for the handling of radioactive materials: A license is required. The issue of the license is not a problem. Don´t hesitate to ask us. If desired, we assist you in working out your application of a license.
In the case of using only labelled DLC and Polymers no license is required.

Which kind of radionuclides and which activity levels are applied typically to radioactive wear measurements?

Investigations of iron materials are often done using the nuclides Co-56 und Co-57 with activity levels of 0.4 up to 4 MBq depending on the kind of machine part and on the measuring problem.
The methods of radioactive labelling have been established for all known metallic materials and alloys as well as for ceramics.
Furthermore DLC and Polymers can be applied. The activities of this materials are far below the free handling limit.
Please, ask us if you want to examine parts of other materials. We will find a way out in most cases.

Can the activated parts immediately used after activation?

Depending on the materials, waiting periods of several days up to 6 weeks are necessary after activation. Hence, a precise scheduling is essential concerning the delivery of the parts to ZAG and the in time return of the activated machine part to the customers.

What happens with the waste materials (contaminated waste oil, activated parts)?

It can be released without problems at the competent local delivery station for radioactive waste. Often the short decay time and the low activity level allow to store the parts until the radioactivity is decayed and than in most cases the appropriate authority allows to dispose the parts with the normal waste . Our staff assists you with finding the correct and cheapest way.
