How X-rays see through your skin - Ge Wang

[@abondonedchannel6870]

Why are most important stuff made by accidents

[@aminetanouyat9643]

Because we are lucky lol

[@buttonpusher3786]

Because you can't predict the result of every experiment and what the result can be used for in the future. Also it was only discovered that way, it's not like the ct scanner was created by accident, it was designed using a huge number of known parts and principles that would provide a desired effect.

Why? because the experiments carried out byt scientists these days are not considered chores.. But in a few 100 years, they may seem simple. RIght now to us they are revolutionary, because our society is advancing scientifically because of these "future chores". Don't belittle those scientists' hard work please.

[@glebkuzmin8062]

Well explained! :) Small correction: Gamma rays and X rays overlap in energies (you can have X rays with higher energies than some gamma rays). The difference between gamma rays and X-rays is how they are produced (gamma rays: emitted from the nucleus, X-rays produced in the "electron cloud").

[@shpongloidia]

The lead aprons aren't enough. You'll need a thyroid guard as well. I just had my thyroid removed two months ago due to thyroid cancer.

[@buttonpusher3786]

shpongloidia There's plenty of evidence to suggest that aprons and other shielding on patients can cause more internal scatter and therefore a higher dose. For that reason a lot of paces don't offer them to patients. Comforters and carers and obviously medical staff won't have an area being imaged and therefore shielding can be used more effectively to prevent exposure. Also the thyroid shield would likely either be in the way of the image or so far out of the way as to be negated as it's such a low dose.

[@alexistzou7447]

Biran Falk-Dotan whats an atomic mass?

[@biranfalk-dotan2448]

Alexier G_G The average atomic mass is basically the average number of protons + neutrons in the nucleus. Most hydrogen atoms have 1 proton and no neutrons, but some can have 1 neutron or even 2 neutrons.

[@alexistzou7447]

Biran Falk-Dotan they are actually called somewhat defferently but i cant remember it

[@VEKTOR_]

Doctors: don't worry, x-ray is safe Also doctors after turning it on: 🏃💨(runs away for protection)

[@VirreFriberg]

It's because their exposure to radiation would be significantly higher than the patients who recieve it considering the doctor would perform 20 X-Rays a day for around 340 while a patient is subject to an X-Ray 1 or 2 times per year.

[@andrewcontreras3130]

[@Bjay723]

Thanks for this video . I was curious about this excact subject

[@shawndrust1413]

No

[@Kathy_Loves_Physics]

The cathode ray depicted is wrong. (He most likely used a "Lenard tube" which you covered but he also had other tubes but none of them had a cross in it with a hinge) Also, as he was creating x-rays from bombarding either aluminum or glass with beams of electrons he was not making "characteristic x-rays" (I think they put it as "rearranging the electrons in the atom and producing x-rays" as glass and aluminum and other low mass items tend to absorb that x-ray and produce another electron instead, called an Auger electron (if you type in Auger electron you can see a nice graph of it).

[@buttonpusher3786]

Kathy Loves Physics I think this is a point at which the video is unclear but bremsstrahlung and characteristic are the two ways they are created in modern plain film use. The video was not clear when moving from his experiments to modern use, likely as it was trying to interest those with limited knowledge of the process and didn't want to complicate what is already a difficult topic.
