"Equally effective" is surely the most appropriate conditional.  These irradiators (Cs-137) are hugely low-maintenance.  If we went to a nuclide with a shorter t1/2, then maintenance costs would go up.  E.g., Co-60 sources would likely need replacement at least every five (5) years, I should think.  If we all installed linacs, or some type of orthovoltage machines, then we would be talking about electronic *instruments*, instead of relatively passive electromechanical devices, and the costs of care and feeding would really go up.  Long story short, if the Feds are going to ask us to do this, they should come up with a very long-term funding mechanism for it.
