Okay, let’s tackle this. So John Makepeace has 46 years of experience in radiation protection, which is a long time. He’s retired, so he’s not looking for a new job. His education and certifications are also notable. An HNC in Applied Physics and RPA2000 RPA, CRadP certifications are not super common. Location is Kingston Upon Thames, England, which is not a hub for high-paying jobs. Considering his experience, education, and certifications, I’d estimate his hourly rate to be around $75, which is on the lower end of the scale for professionals with similar experience and education.
