Earn your radiology certification with clinical precision
MIOSHA Radiology Pro is a structured, regulation-grounded training program for limited-scope operators — covering radiation physics, ALARA safety, digital imaging systems, and patient positioning so you can step into the X-ray suite ready to perform, not guess.

Every exposure decision you make has a consequence — my job is to make sure you understand exactly why, so you never have to guess in the room.

Dina Williams
If you're stepping into a limited-scope radiology role — or you've been in one for a while and realize your training has gaps — I want you to know something: that discomfort you feel around radiation safety protocols, exposure settings, or image critique is completely normal. Most allied health workers are handed a credential pathway without anyone sitting down to explain the why behind the rules. This program exists to fix that.
I built MIOSH Radiology Pro because the standard of care in radiologic practice demands more than checkbox compliance. It demands that you understand what ionizing radiation actually does to biological tissue, why the ALARA principle isn't just a regulatory formality, and how every decision you make at the console — your kVp, your mAs, your collimation — either protects your patient or adds unnecessary risk. When you understand those connections, you don't just pass an exam. You become a practitioner other clinicians can trust.
The curriculum is structured the way real competence is built: foundation first, application second. We start with radiation physics and biology so the safety rules make sense. We move through MIOSH compliance, occupational dose limits, and documentation so you understand exactly what's required of you legally and professionally. Then we get into the equipment — CR and DR systems, exposure factors, image quality evaluation — and finally into patient positioning and retake reduction, where all of it comes together in actual clinical practice.
I've kept the language precise and the procedures explicit, because that's what this field requires. There's no room for vague instruction in a radiology suite. Every lesson is written so you can follow it, apply it, and — when you're standing in front of a patient — execute it with confidence.
If you're preparing for your limited-scope certification exam, working toward continuing education hours, or simply trying to bring more technical authority to a role you already hold, you're in the right place. Let's get you there — step by step, the right way.
