Is gamma radiation expensive?

Could you please elaborate on the cost associated with gamma radiation? I'm curious to know if it's a costly process or not, and if so, what factors contribute to its expense? Is it the equipment required to generate gamma rays, the safety measures needed to protect personnel, or perhaps the specialized training that's necessary to handle such equipment safely? Additionally, does the cost vary depending on the intended use of gamma radiation, such as medical treatment, research, or industrial applications? Thank you for your insight.
