3. Source disposal costs
Only authorized companies can help with the disposal of the source. Some licensees do not know where to go for disposal of the source and need to search for an authorized company or responsible authority to carry out the work. This could result in high costs, for example: between 2,000 – 7,000 US$ in the United States. This is only if there are no additional costs to solve safety problems with the radiation protection shielding. The company will check the sealing first to make sure that there is no leakage of RAM. Local disposal can lead to great expenses, therefore usually the industry is searching for a local RAM manufacturer with a good reputation and with capabilities to dispose of RAM that they manufacture.

4. Rules for inspections
Some countries mandate users of radiation sources to hire authorized companies to periodically inspect the outside of the source for radioactivity leakage.
A certified company takes samples from the radiation protection shield and shares the results with the client and local authorities. This inspection is called a wipe test or a leak test. First, the surface of the protective shielding is covered and cleaned with an ethanol solution, then a cotton swab is used to check for surface contamination (e.g. with a cobalt-60 radioactive isotope). Records are reviewed and approved by inspectors and are kept for a certain period (e.g. three years).
5. RSO certification
Governments, agencies or commissions are responsible for conducting Radiation Safety Officer (RSO) courses. These regulations are part of IAEA guidelines and agreements.
Employees have to be trained to handle radiation sources and safety procedures on site. They attend RSO training courses periodically which are paid by the company. When an RSO leaves the company, a new employee has to be trained. At least one radiation safety officer needs to be on-site. If an RSO employee is temporarily unable to work, this could result in difficult situations.
There are a lot of regulations for companies who want to work with radiation sources. Before buying a radiation density gauge, the buyer should be informed by knowledgeable parties for the selection of RMA manufacturers with a good reputation to decrease the risks for high costs in the end.
Please note that the regulations can be different for each industry and region, depending on the restrictions of local governments. There are certainly more regulations and issues to mention and not all are included in this list.
