I think you are getting a bit confused, Jim's post splits Clinical Technologists into two groups. Engineering Technologists (MTO's working in EBME etc) and Physics Technologists (MTO's working in Radiotherapy, Nuclear Medicine, Radiation Protection etc.) Clinical Scientists are already state registered by the HPC and can be found in both Clinical Engineering or Clinical Physics specialties.
If the HPC are worried about the different educational requirements maybe they should look at whether the Physics Technologists minimum requirement should be HNC/HND and not try and force the Degree reguirement on Engineering Technologists. Remember this is only a minimum, if departments want to employ people with degrees they can still do so and write the job descriptions accordingly.
