Sorry if I’m not supposed to be here. Just want to know if effective dose is a real thing. Because I’ve recently been told by someone who is APPARENTLY a radio biologist that it’s not. He says it’s basically a made up and flawed concept that is used to deceive the public into agreeing to CT scans bc if they understood that the real amount of radiation they’re getting is the DLP, and that CTs are causing a lot of cancer cases, neurological disorders, chronic diseases, Alzheimer’s etc. then no one would want a CT scan and it would be a failing business. I’ve had two CTA PE protocols in the last month. The first one was DLP 500+ mgy*cm second one was a little less at 400 something. CTDLvol was 22 mgy for both. If that’s the amount of radiation I really received in a months time.. that’s extremely concerning to me. I’m also confused about if the DLP number on the report is adding both scans together (with contrast and without) or would the true DLP for my scan be double what the report says? I’ve read that a rad workers yearly max safe dose is 50msv. So for me to be exposed to this amount in just two scans seems like .. a death sentence? I don’t really understand effective dose. How a total DLP can be so high but effective dose be low. Is it like saying “you are going to absorb 500 mgy of radiation but only 20 might hurt you”? Seems unbelievable. The “radio biologist” said its 2021- the truth is going to start coming out about CT and all the cancer causes and the true risk. He advised that people who’ve been scanned get regular blood work and a full body MRI at least every 2 years to try to catch the radiation induced cancer early, to pray and hope for the best.... I just have no idea what to think. Any input or clarification is appreciated.
