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.

man, in those times, these weren't considered chores. I doubt you consider these chores. Right now everyone could be winning noble prizes, but we don't.. 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.

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
@buttonpusher3786 5 лет назад
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.
