Called the Stemrad 360 Gamma, the belt could be a lifesaver for the emergency services in a nuclear accident. Oren Milstein, the co-founder of Stemrad, says it’s partially made out of lead and is designed to first and foremost protect the pelvic area, where most of the body’s renewable bone marrow is made, Reuters reports. “It may look simplistic on the outside but the structure inside is three-dimensional and very unique. The idea here was to create a product that on the one hand protects but on the other hand is not overburdened by weight,” he said. Nobel laureates Roger D Kornberg and Michael Levitt are on Stemrad’s scientific advisory board, as they were quickly persuaded of the belt’s merits. “When I first told about it, I was at first skeptical,” said Kornberg. At just over 15 kilos, the belt would be wearable for most people. A full body suit to protect all the body’s vital organs such as the liver and thyroid would weigh about 200 kilos, so most people wouldn’t be able to wear it. The belt can protect the wearer for doses of up to 1,000 rads – a high level of radiation poisoning that can cause serious illness and even death. Milstein says that protecting the body’s bone marrow is crucial to ensuring survival after radiation exposure.[/QUOTE]
So it protects the marrow in the hips? Clever idea.
200 kilos holy fuck
How does one stop gamma radiation, strong electromagnetic field?
[QUOTE=mdeceiver79;44506267]How does one stop gamma radiation, strong electromagnetic field?[/QUOTE] Lead or a lot of paper. a lot.

[quote] The belt can protect the wearer for doses of up to 1,000 rads – a high level of radiation poisoning that can cause serious illness and even death.[/quote] That's a dose of 10Gy, corrected dose for it being gamma is 10Sv assuming total body irradiation, you'd have to weight it if not total body irradiation.
This seems fucking useless unless you just happen to be wearing it WHEN a nuclear explosion occurs and you also just happen to be in a direct line of site from the explosion. Post detonation the main concerns you have are alpha and beta radiation which the dead layer of skin cells on the surface of your body quite easily absorb anyway. Any highly penetrating electromagnetic radiation has already passed through you and is of no more concern post detonation. I don't think the x-rays or gamma rays given off from radioactive nuclei relaxing to their ground state is really much of a concern to be honest. You're biggest concern is the radioactive dust floating around which this belt isn't going to do shit against.
[QUOTE=mdeceiver79;44506267]How does one stop gamma radiation, strong electromagnetic field?[/QUOTE] You attempt to attenuate it all. Put a huge amount of mass in the way (typically boron concrete, as is used in radiotherapy suites) and if you have enough, you'll attenuate the majority of the photons. There's a load of figures that can be done to figure out, on average, how much is attenuated. For personal protection in lower amounts, we typically use lead aprons, thyroid shields, gonad protectors and such which used to have lead slips / lead infused rubber, but I believe often now use barium inside instead. Protection is normally given as "equal to x mm of lead".
[QUOTE=mdeceiver79;44506267]How does one stop gamma radiation, strong electromagnetic field?[/QUOTE] Lead. You can't influence EM radiation with an EM field, dummy. The idea is that since the biggest problem with gamma radiation is that it kills your bone marrow, you protect the most valuable area (it still dies in the rest of your body). It's just a really fancy belt made of lead.
It's quite nasty that the only protection against gamma radiation is just putting as much dense material between you and the source. Which is pretty fucking heavy if you have to wear it.
[QUOTE=Awesomecaek;44506310] It's just a really fancy belt made of lead.[/QUOTE] I made a sarcastic comment a few posts ago about it being a lead belt but deleted it since it seemed bitchy. I still can't believe they have managed to sell a lead belt to people, its hilarious.
[QUOTE=Clavus;44506329]It's quite nasty that the only protection against gamma radiation is just putting as much dense material between you and the source. Which is pretty fucking heavy if you have to wear it.[/QUOTE] Gamma radiation just doesn't give a shit.
[QUOTE=Awesomecaek;44506356]Gamma radiation just doesn't give a shit.[/QUOTE] gamma rays* it isn't like alpha or beta radiation.
When I see this, I think of that containment belt in Beyond: Two Souls.
[QUOTE=Dark One;44506375]gamma rays* it isn't like alpha or beta radiation.[/QUOTE] Uh, it is? There are three basic kinds of radiation which basically amount for alpha radiation which is helium ions, beta radiation which is free electrons, and gamma radiation which is gamma rays.
[QUOTE=Awesomecaek;44506424]Uh, it is?

[QUOTE=Rct33;44506450]There is also proton and neutron radiation, but that is pretty rare[/QUOTE] there is also Chinese radiation but that was only discovered this century and they don't know much about it at the moment besides I thought the Israelis specialty would lie in gas masks not radiation protection
Got x-rays as a form of ionising radiation too, if we're listing common types.
[QUOTE=Antlerp;44506466]there is also Chinese radiation[/QUOTE] What. [QUOTE=mdeceiver79;44506342]I made a sarcastic comment a few posts ago about it being a lead belt but deleted it since it seemed bitchy.

Even the manufacturers of those "anti-radiation" stickers you put on your phone have probably made millions. E: I just found a great way to make money. Maybe I should manufacture anti GMO-stickers that protect you from dangerous radiation from GMO products and a spray that turns bad processed foods in to good organic ones.
1000 Rads is a feel-good number. Such a dose would normally (probably) be fatal but there are so many fucking factors to this that it's impossible to even accurately model such a thing. And radiation poisoning is not going to be avoided by just shielding your crotch. It may protect you from some forms of cancer, but the thyroid is still going to be the biggest problem, and 1000 rads over anything less than a day has a good chance of killing you whether or not you have a lead g-string.
The full-body suit is 200 kilos... So why not integrate it with a powered exoskeleton?
[QUOTE=JgcxCub;44506821]The full-body suit is 200 kilos... So why not integrate it with a powered exoskeleton?[/QUOTE] This is supposed to be a safety measure in case of emergency. Real life isn't Dead space. You can't just waltz into a closet and come out in an exoskeleted 300kg suit in a jiffy. [editline]10th April 2014[/editline] If you need to do stuff in an irradiated area it's just better to send a robot nowadays.

It's meant to function as a belt that offers protection against radiation in-case of a nuclear accident, presumably in various contained nuclear facilities, which belts such as these will most likely be prepared and stationed on-hand to those who are at danger of such accidents happening. Just because it doesn't offer universal, fail-proof protection against radiation doesn't make it 'fucking useless'.
[QUOTE=Falubii;44506926]He is right that physically they are quite different, one being light and the other two being energized particles.[/QUOTE] Well yeah but they are all called α [I]radiation[/I], β [I]radiation[/I] and γ [I]radiation[/I]. Because they all [I]radiate[/I], even when their nature is different. You could say that γ radiation is a release of γ rays.
