Are our knives radioactive?

Lol...uranium is soft ...like lead only 2x heavier...ALL metal is somewhat radioactive since the use and testing of fissionable material. It gets into the atmosphere...settles on the ground and equipment...and is then used in remaking new metals. The level is not very much however. All new and recycled metal manufactured after the 40's is more radioactive sorry to say. "Sonnydaze" is right about the Radon...get your basements and crawlspaces tested....
 
For what it's worth, I just ran my Spyderco Tenacious under a geiger counter and it did not reveal radiation.
 
If this is truly a concern than we should all stop using cell phones. Im just sayin.

Guys, if you are going to worry about trace amounts of radioactivity, kill yourselves now. Radioactivity is everywhere. There are radioactive isotopes of iron that are actually a bit hotter than co60. For that matter, there are naturally occurring radioactive materials in soil, water and air. Have you ever gone outdoors during the day? You were bombarded with solar radiation. If you only go out at night, you get cosmic radiation anyway. If you get ahold of a low level radiation detector like the Navy RM-3, you'll soon discover it never shuts up as long as it is turned on.

Was reading an article in the New York Times http://www.nytimes.com/2010/04/24/world/asia/24india.html?_r=1 and got to thinking about the safety of our metal imports.

Many of us own knives which were manufactured overseas but how do we know without testing that the metal used in our knives is not radioactive? Hope this post is not interpreted to stir up fear mongering. That is sincerely not my intention. It's just plain curiosity. I would suspect that radiation detection is probably not done at the country of origin.

From what I could gather in doing a search, the government is in the process of installing radiation portal devices to detect nuclear contaminated imports. Apparently 100% of imports will be scanned but I could not verify that that is presently the case.

And this from a German news website: "German authorities in recent months have found a disturbingly large amount of radioactive steel in factories across the country. Much of the contaminated metal is thought to have originated in India."

Any comments?

I wondered this same thing about every Japanese car imported, and everything else, after the Tsunami. For this reason, I will not buy a new Japanese car. BUT the tragic truth is, there's really no escaping the effects of it worldwide. They dumped TONS--repeat TONS--of radioactive waste into the ocean. You do the math. Great topic, but one we can't do much about. I spoke to a friend the other day who said that after the Tsunami, US authorities dramatically raised the acceptable levels of radiation for everything in the USA. I have not verified that, because I do not know where to find the info. Does anyone here know where to find that info? Finally, at the end of the day, crazy as it sounds, this has happened before--Chernobyl, 3 mile island, WW 2, and others... and it's the world we live in. However, I will never let anyone convince me that nuclear power is safe. It's all about the money, even at the expense of the world itself. Whew! Heavy topic!

I THINK THIS ONE IS RADIOACTIVE.
I took this pic in the dark! Look at the glow!
 
When I was about 7 or 8 I made a bathroom sink mixture of all the medicines and chemicals that were under the sink. I made it to pour on the ant hill out back, but it didn't kill them. After a couple more tries with the bathroom stuff I switched to gasoline and found that if you pour it in there and don't light it it actually kills them. There was no radio activity involved, but there may have been mutations jk.

You'd just need a proper coating. ;)

I'd say that waste is very well distributed and won't cause any damage at all. Even if it was 1000 tons - our oceans should be big enough so that it won't matter at all.
I bet it has killed and harmed a lot of fish and other stuff in Japan but BP did the same in the gulf...
 
If it is really a threat, i think it is brilliant. Remember some of the older military sayings ? Artillery--Death from afar, Air Force--death from above, Head Cook--Death from within. Well here is the new one: Not making it yourselves anymore & importing it ?---Death from afar & within.

pet food
kids motorcycles
toothpaste
baby formula-liquid
baby formula-powdered
vegetables
beef
chicken
paint
& now steel

^^^Things that have been shipped to the US that contained toxic waste of some sort.
 
Anything that is carbon based has some level of radioactivity. I cut my grass today and recieved more radiation than I will ever get from my knives.
I can't worry about this. Maybe the obama (not capitalized due to lack of respect) administration could make all radioactivity illegal. Or better yet how about a radioactivity tax?
 
Pretty sure my tritium titanium pendant and tritium Traser watch gives me more radiation than any of my knives. Kind of curious why I haven't found custom knives with tritium vials in titanium handles yet. Might have to pitch that idea to Chris Reeve:D.
 
I once "convinced" a concrete shoring contractor to let me borrow his wheel barrow. I stuck my survey meter to the nearest concrete column and (on the lowest setting) the needle moved to about half way across the scale. I told him I'd keep quiet if he'd let us use his gear. Concrete with fly ash in it is detectably radioactive. Most concrete has fly ash in it now.

Radioactive means ionizing radiation. Cellular phones radiation is not within that definition.

The biggest problem along these lines is Co-60 sources are scrapped and find their way into iron/steel.

Most scrap metal dealers have radiation detectors at their gates. I worked in the phosphate industry which has what is called NORM, naturally occurring radioactive materials, natural uranium and their daughters.

FWIW, you can breathe radon all day. It is not a hazard, but its daughters are, so the hazards start when the Rn decays. Its halflife is 3.85 days. We didn't get a big scare from it as there were no deep pocket companies that could pay for remediation.

The red Fiesta Ware dishes had a radioactive pigment. It was good for radiation show and tell shows. Red was my favorite color and as a kid I always used the red dishes. That was >65y ago.

What has not been pointed out is our bodies contain measurable radioactive isotopes. Been that way.
