Ok, its time to calculate our total radiation exposure. In the process, you can find out all sorts of things in your day-to-day life that might be giving you that little extra glow.
Here’s the radiation calculation chart from the EPA. My own exposure came out at 325 mrem. To make that comparable to the radiation exposures reported in millisieverts (mSv), one millisievert equals one hundred millirems. Here’s a calculation program. The trouble is that the reporting in mSv makes it hard to compare things in terms of dosage.
I’m also going to say that the EPA calculation seems a bit off. They allow for 14 mrems of exposure from any “nuclear medical procedure.” Really? Here’s the handout for radiologists in terms of radiation exposure. I quote: “CT procedures range from 100 to 4,000 milli-rem, not much less than the lowest doses of 500 to 2000 milli-rem received by Japanese survivors of atomic bombs.” Dr. Boyar goes on to promote the newest technology. If you can slog through the following quote you’ll see why.
“Marconi (Marconi Medical Systems, Inc. 595 Miner Road, Cleveland, OH 44143) reportedly has calculated the typical patient dose received when performing their non-FDA approved cardiac calcium scoring protocol when performed on their single slice spiral CT scanner using the Win Dose program. In their cardiac calcium scoring protocol (130 kV, 200 mA, Spiral, 1.25 pitch, 77 images) the effective patient radiation dose delivered to the patient was 4,300 milli-rem, equivalent to over 200 chest x-rays. It would take more than ten years to absorb this amount of radiation from the natural background radiation sources of sun and soil. In contrast, the Electron Beam CT Scanner delivers only about 70 milli-rem of radiation to the patient when acquiring images for the coronary calcium scoring exam.”
Ok, I’m sold. Let’s get the newest scanners now. But what does the EPA think it’s doing by telling people their exposure from nuclear medical testing is only in the fourteen mrem range? It’s clearly much higher than that.
If they are that far off on the known risks, it does lend a certain level of common sense concern that they may not be adequately addressing unknown risks. The National Council on Radiation Protection and Measurements (google book link to Ionizing Radiation Exposure using nuclear testing fallout mrem search) estimated that the average exposure of the population of the Unites States from weapons testing would be fifty three millirems, not the one mrem estimated by the EPA. I’m feeling a little paranoia, are you?
