In summary, all else being equal, white would be the best color to wear if you are exposed to a nuclear explosion.

All else being equal, which color clothing would be best if you are exposed to a nuclear explosion (far enough away where you're not instantly killed, but still subjected to significant radiant energy)? Black or white?

It seems like black clothing would get hotter and could thus burn you by contact, but would it also absorb more radiant energy (e.g. high energy photons) and thus protect your skin better?

(I wasn't sure which forum this would belong in so feel free to move to the appropriate one)

Setting aside the whole 'what do you wear to a nuclear explosion?' amusement, the generally best clothing to resist EMR is white.

Well, barring silver foil, of course. But next to silver, white is the most reflective.

High-energetic photons won't care about the color of your clothes. Color is a reaction to visible light. All other things being equal, reflecting more of this light is certainly useful -> white.

I remember reading that some Hiroshima victims had the pattern of their clothes burned into their skin.
So an all white sheet is probably the best thing to wear, plus it simplifies the funeral arrangements.
Do note that the thermal pulse from a thermonuclear device is enormously greater and lasts much longer, so the color of the garments is probably immaterial. Witnesses to the Pacific test series reported sea birds bursting into flames in mid air, some miles from the explosion.

Any clothing that can protect you from intensive thermal radiation/shock will help. Color of the suit isn't critical. Here is a typical suit for electricians:

Unfortunatelly, such clothing won't be enough to shield you from powerful ionizing radiation (gamma rays, protons, neutrons etc.)

There are clothes with lead to shield x-rays. They don't absorb all gamma rays, but they would still give protection. Especially with multiple layers, they'll also provide some protection against the shock.

bright orange or yellow - you'll die for sure anyway, but you body will be easier to spot and be burnt as rottening radiactive waste. otherwise, you can also put on something very flammable, so, you'll go though all of it faster and reduce decontaminators' work.

The color won't matter much but a nice thick wool coat with full biker leathers would be my fashion choice.

Lead is gray, so I'd say the best color to wear is gray.

Special kinds of electricians:), working in vicinity of medium voltage live circuits where arc flash hazard is deadly in radius like 10 feet

All very interesting answers, but...

I'd reiterate the user's specification that "...all other things being equal..."

i.e. he knows that there are lots of variants on protecting onesself. Those variants aside, he's interested specifically in colour.

Though frankly I still can't imagine why.

It's like saying:

'All other things being equal, which is the most aerodynamic position to hold your hand in, if you stick it out the window of an airliner doing 500mph at 40,000 feet?'

'All other things being equal, what is the best scent to be wearing to discourage the rabid grizzly that is currently savaging your head?'

'All other things being equal, which species of whelk stands a better chance in a supernova?'

I think a neon color would be best. Not because it will reflect more light, but because there is so much energy in a nuclear explosion from EMR that the color of your shirt probably won't matter much. However, if your shirt is a neon color, you'll stand out from the dust and rubble and it will be easier for a rescue crew to find you. Unless you're very close to ground zero (in which case your shirt will evaporate along with the rest of you), it's going to be collapsing buildings and falling debris that threaten you much more than radiation or heat, so prompt medical attention is going to be important.

In that vase, the best thing to wear would be a helium balloon on a 20 foot string.

Your question, and the responses you received, such as this:

... is what has me joining this forum. Congratulations. I *thought* for a moment you'd not received an actual answer, but I think mfb captures it:

If you wore black, you're right, it would absorb the light, but then your t-shirt would probably burst into flames or at least give you a nice contact hig... er, contact burns. But, mfb also hits the nail on the head that visible and IR light are small components of the energy release of a thermonuclear event, which releases far more in gamma radiation, plus those pesky extremely energised alpha and beta particles all of which will not give a tutti-fruiti dang what colour t-shirt you're wearing. Hello, thyroid cancer!

Is it wrong that this make me gaffaw out loud?
Fascinating answers everyone.

LMAO I forgot those old civil defense Vids were so funny.

watch both houses! the roofs are partially blown off but only one burns... never mind you've received a most likely fatal amount of radiation poisoning but your house did not burn down...


wounder if the guy's seen checking the aftermath without protective suites had Geiger counters supplied to them before they went in?

I read about the pattern of people's clothes being burned into their skin, as well.

My conclusion is slightly different, though.

I'd wear this T-shirt:

I just shake my head every time this featured thread shows up at the top of my page. After all, what good is the color of your clothing if you aren't wearing 2 million SPF sun block to go with it? :oldconfused:

So that you stand out from the hoi polloi when the first Army helicopters arrive to survey the scene, I think you should wear coveralls of fluro pink, emblazoned in large letters "PLUMBER-GASFITTER-ELECTRICIAN", because we know the army gives priority to qualified tradesmen! :)

Same color as the launch crew.

I also thought a dirt color would be optimal. Perhaps 3-4 feet of it between me and whatever. Perhaps with layer of white Borox to capture neutrons.
 

1. What color clothing is safest during a nuclear explosion?

During a nuclear explosion, it is important to wear clothing that provides protection from the intense heat and radiation. The safest color clothing to wear is light-colored, loose-fitting clothing that covers as much of the body as possible.

2. Why is light-colored clothing safer during a nuclear explosion?

Light-colored clothing reflects heat and radiation better than dark-colored clothing, which absorbs and traps heat. This can help prevent burns and other injuries from the intense heat of a nuclear explosion.

3. Is there a specific color that provides the most protection during a nuclear explosion?

While light-colored clothing is generally recommended, there is no specific color that provides the most protection. The most important factor is the material and fit of the clothing, as well as any additional protective gear such as a gas mask or goggles.

4. Can I wear any type of clothing during a nuclear explosion?

No, not all types of clothing will provide adequate protection during a nuclear explosion. It is important to avoid synthetic materials, as they can melt and stick to the skin. Thick, natural fabrics such as cotton or wool are recommended for maximum protection.

5. Are there any other precautions I should take with my clothing during a nuclear explosion?

In addition to wearing light-colored, loose-fitting, and natural-fiber clothing, it is also important to cover as much of the body as possible. This includes wearing long sleeves, pants, and closed-toe shoes. It may also be helpful to have a change of clothing and a spare set of protective gear in case of contamination.
