do radiation protection gloves actually protect you in a primary x-ray (85kV, 100mAs) beam?!

[willman20008]

whereabouts did you do this? what do you mean by 'reroute the transformer power?'

[bionerd23]

@willman20008

there's one transformer that feeds two x-ray stations. you can re-route the power to either station, but cannot use both at once.

[willman20008]

whereabouts did you do this?

[mbthepixelkiller]

What means 100mAs?

[bionerd23]

@mbthepixelkiller

miliampere-seconds, so it's ampere multiplied with time.

[1ownjoo2]

Hey bionerd. What are your takes on the Nuclear Reactors in Japan ? Somehow i dont think they are telling us the whole truth about those explosions. Claiming the containment vessal is still intact. I dont believe it.

[bionerd23]

@1ownjoo2

not sure. the first explosion may be a hydrogen explosion indeed, but the second explosion was so heavy, with stuff blown up so far, i'm not sure what to believe. maybe a heavy hydrogen explosion...?

after all, those reactor containment vessels can take a lot, they're the safety barrier that chernobyl did NOT have at all.

however, i think it's downright impossible to judge what is REALLY going on just from pictures and news, as humans are known to be full of shit and lie.

[1ownjoo2]

@bionerd23

I personally hope this doesnt mean the end for building more Nuclear reactors. Im a firm believer that we need to invest into building thorium reactors. They are much safer and the amount of energy generated from thorium vs uranium is vast.. Politicians are so stupid... Fear what you dont understand.. India is building thorium reactors, why isnt the United States... so stupid

[bionerd23]

@1ownjoo2

exactly, i agree. uranium reactors are a replacable risk now, though, at least and especially in our countries (USA, germany). well, i think i'll have to do a video statement about this. check beck in a few hrs.

[83CyborgX1]

What exactly are the lead gloves ment to be used for? Changing source needles of the machine for the cancer therapy?

[Imabug01]

@83CyborgX1 the most common use for lead gloves like these are for restraining patients when necessary, particularly small children that can't or won't hold still for an x-ray

[bionerd23]

@83CyborgX1

lol no, changing those sources for radiation therapy can only be done remotely (robots arms visible through lead glass), for example, or entirely machines. the gloves would still offer no sufficient protection by far!

however, as people said before, those gloves are used to e.g. restrain patients or when you need to operate under x-ray control.

[pomulitos1]

nice experiment

[gccn]

I'd like to see the one about the person standing next to a patient; my oncologist never wears protection and does extreme tests himself on cancer patients. I always wondered if he glowed in the dark or not.

[NoWattz]

It is obvious that the lead glove provided the most protection. Is that because of the different densities (or atomic numbers) of the materials or because of the actual physical thicknesses of the gloves themselves? Also, if lead is more effective because of simply density, would more dense materials like depleted uranium, tungsten, or even gold offer more effective radiation shielding than lead?

[Knightyme]

@NoWattz I would say most likely the denser the material the better shield it would provide. But lead is a cheap material compared to the others mentioned. If you used a gold glove I would be unsuprised if they kept going missing for some odd reason. :)

[bionerd23]

@NoWattz

well, it may also be that the lead glove is physically thicker than the bismuth glove. too bad i cant find numbers on it. but yeah, the more dense a material, the better its shielding properties. they use depleted uranium for shielding highly radioactive substances, e.g. Ir-192 for brachytherapy (cancer irradiation therapy). depleted uranium is a very good radiation shield for very highly radioactive material, as it's only very weakly radioactive itself.

[vk2zay]

What about barium sulfate shielding ware?

[nodariel]

I like how the interference on the camera was greatest when it was uncovered. Would that be x-rays reflected from the dosimeter?

[bionerd23]

@nodariel

not sure if it was greatest then; might've been that the search light was still on and most of it hitting the gray table, which again lead to a different color and brightness correction of the camera (you can see it almost instantly adjusts to different lighting levels). but yeah, surely x-rays got deflected by the dosimeter as well as other objects within the beam (e.g. the table); the probability of various interactions is also dependant on the atomic mass number of the matter.

[iammrpope]

its a shame you expose yourself to all this radiation, your children would be brilliant ;0

[bionerd23]

@iammrpope

it's not necessary my children would be like me... well, unless i managed to clone myself, maybe. otherwise, there's always 50% of foreign DNA mixed into mine, which could lead to somebody who likes e.g. arts, blergh. :P

asides, i dont like children much anyway, well, at least until they're at least 15 yrs old or so (depends on brain development, not so much on physical age). :P

oh hey, but just fyi, i wasnt exposing myself to any radiation for this very experiment. ;)

[PsychoticBovine]

@bionerd23 I don't like children much, either. And I am sure you take precautions when working with these machines. Also, I don't like clowns, but that's a story for a different comment.

[geonerd]

@bionerd23

Arts? Right brain activity?!?? ARGH!!

C'mon, give it a try; just a small dose. Remember, not ALL mutations are harmful... :)

[bionerd23]

@geonerd

that's true, but i dont wanna push my luck by moving from a stochastic to a deterministic damage dose, as very high acute doses ALWAYS make you ill (or, in other words, cause a whole lot of negative effects).

i'll see about the mutations (stochastic changes) later, i guess. maybe i'll become or supermutant, or maybe i'll just die of cancer... but whatever it is, you can be sure i'll post it on the internet! =)

[geonerd]

@bionerd23 OK, just so long as there's a video for your demanding fans to watch! LOL!!

[gccn]

@bionerd23 You'd love my little girl. She's like a mini mad scientist. :D

[iammrpope]

@bionerd23

well ill be that 50/% genepool, i like arts and blargh. rearing the kids to 15 wouldent be so bad, you could teach them to appreciate science and thinking for themselves, teach them to change their diapers and what have you

[1ownjoo2]

I thought radiation only goes the way its pointing. Why was the camera getting all fuzzy if it wasnt in the beam of the x-ray ?

[bionerd23]

@1ownjoo2

it's called "stray radiation". radiation interacts in many different ways with matter, which leads to the x-ray photons being scattered - and quite a lot so! there are many different ways for radiation to interact with matter, depending on the type of radiation as well as the energy. photons / x-rays can even SPLIT ATOMS if they have enough energy (photon-induced fission)! google for "interaction of radiation with matter" if you want to know more; check e.g. the sprawls-org link.

[geonerd]

Wow, the numbers are quite a bit higher than I anticipated. I guessed a 40% reduction for the lead shielding. Cool test!

[onthecuttingedge2005]

that camera picks up the X-Rays pretty good.

[alfaradiation]

Good demonstration of the protection gloves protection. I didn't saw any gloves yet so how thick are lead gloves and what brand of dosimeter did you used :).

[bionerd23]

@alfaradiation

i'm not sure about the lead gloves, i couldnt find any readable piece of information on them, lol (unlike the bismuth gloves, the lead gloves are NOT mine). i'll let you know if i can find out.

the pen dosimeter is an "SEQ 5" (google this: "SEQ 5" DOSIMETER and see first link / pdf file).

[Imabug01]

@alfaradiation Lead gloves are usually 0.5 mm lead equivalent thickness

[Ignare]

Great vid. Keep up the good work :)

[syranon]

nicely done, i'm curious if i'll encounter a situation where i need to remeber this =)
