  • You’re mostly right.

    The issue is that the ALARA (as low as reasonably achievable) principle has been improperly applied and has quietly over time changed to leave out the “reasonably” part. So regulations and protective measures have gone for as low as achievable period.

    This is in part driven by fear of nuclear radiation –stemming from the Chernobyl disaster, Fukushima and others– and the application of the LNT model (linear non-threshold).

    That’s where we meet another issue: we actually have no idea what low levels of radiation exposure do to a human body. There very well might be threshold, after which the risk becomes linear. All we know about the effects is based on studies on high radiation dosages from the nuclear bombs at Hiroshima and Nagasaki. Yet we have applied the linear risk of cancer we found in those studies and simply drew the line in the graph from the lowest risk we observeren down to zero, which gives us the LNT model.

    The article kind of makes it seem like this model is proven fact, but for the lower exposures, which is basically all we’re dealing with at nuclear facilities, it simply isn’t.







  • LOL, why is it so hard to accept the fact that you’re wrong? Or that your information is outdated? Have you always been like that?

    And I am “pushing for doctors of a fluoroscope”. WTF is this sentence?

    Mate, a fluoroscopy is a type of X-ray-based exam where the doctor wears the garment. That is the indication for lead garments, to protect other people in the room from scatter radiation coming off the patient at the time of the exam.

    The lead shielding is in the X-ray machine itself. Not on the patient. Your information is outdated.

    So again for the umpteenth time, next time they give you an apron tell them to properly collimate instead. Because lead aprons can actually increase your dose.






  • Yes. The patient isn’t supposed to wear a garment in general is what I said. Again, read please.

    And “modern” is anything that was built in the last 50 years or so. So no, it’s not common practice to put lead garments on the patient and it’s simply a matter of the technologist being too lazy to collimate properly.

    Mate, you really need to read better LOL, like I said in my first comment, it’s for fluoroscopy or X-ray assisted surgery

    And the lead garment was bullshit as I have been telling you for a bunch of times now. Read up about x-ray machines and collimation before you accuse someone of not knowing what they’re talking about because you had an X-ray a few times xD



  • Like I said, collimation is what’s key: if you don’t put other body parts into the beam there is no need to put lead on a patient. Lead garments don’t work for the patient. It only helps to protect others around them from radiation that’s scattered in the patient and coming out at different angles.

    So next time they hand you one, ask them to properly collimate instead.
