Probability Of Receiving A Harmful Dose Of Radiation


Recommended Posts

As far as I know, radiation exposure is negligible unless you spend a lot of time doing fluoroscopy-guided procedures in the room (as opposed to behind the shield). Basically, that leaves only interventional radiologists (who have lead goggles, thyroid shield, vest and apron) - and there are other specialists who also regularly do fluoroscopic procedures.

TMP alone along with dapsone can be used for treatment of PCP in the context of sulfa allergy.

Going away now.  ^_^

 

ha :) 

 

we just covered this at the HUDA physics review course here in warm and sunny Texas (sometimes the resident life is not that bad).

 

It is indeed incredibly rare. The vast majority are well less than 10% of the yearly max radiation exposure (which is getting about as much as a full abdo/pelvic CT).

It might be a different story for interventional radiologists, cardiologists, vascular surgeons and neurologists. There have been studies showing increased rates of brain tumors and lymphomas in interventional cardiologists, specifically left sided.

Rad oncs are probably the most at risk of radiation induced secondary malignancies I think. Especially in brachytherapy (handling radioactive sources for implantation). These are therapeutic doses of radiation, not diagnostic doses. We wear dosimetry badges that monitor our radiation exposure. What I can tell you is its small..... The highest risk people are actually the radionuclide technicians and even they don't register anywhere close to significant levels of radiation exposure.

 

Also don't mistake correlational studies on rate of malignancies in physicians for causation. There is a principle called ALARA that all of those guys follow almost fanatically. Hard to get meaningful doses of radiation unless its by accident.

Only the brachytherapists though and even then we are really only directly exposed to XRT when doing LDR (or if our HDR unit had an accident). Unless the glow from my monitor when contouring is a significant dose :P
