In total, 30 days of IMRT will be 60Gy, which if received in the entire body in an instant, would be fatal within 24 hours.

spankmeister posted:2000mSv as in milli not micro? as in 2 whole Sievert? The way it works is that they have a beam-forming mesh on the end of the accelerator which is then spun around the patient, so that only the place where all the beams cross gets the full dose. This area is calculated using a mix of PET-CT and MR scans, and are done by a medical professional with a specialty in particle physics using a computer. During their break, I got to talk a bit with the person who does the work at Aarhus University while I was in cancer therapy. It was absolutely fascinating.

Data caps are such a foreign concept to me tbh. Never had one on my home connections, but sometimes my mobile provider sends me a text like "you've used up 50% of your data this month!!" and I think "yeah? that's what it's there for?"

did the cymbals video have captions? i watched through awful.app and had no option. i just want to know the material used. i assuming steel because of the 800 degree furnace. i always thought cymbals were made from brass or bronze.

Are you asking for the source of the video (it's a youtube video; you can just click on it) or a source for the assertion "this dude simply loves steam engines", because neither of those things make sense
