Can normal objects become radioactive? 🤔 The short answer is yes, normal objects can become radioactive under certain circumstances. In this article, we will explore how this is possible, provide examples, and address common misconceptions surrounding radioactivity and everyday items.
##Understanding Radioactivity
Radioactivity is the process by which unstable atomic nuclei decay and emit radiation in the form of alpha particles, beta particles, or gamma rays. This radiation can ionize atoms and molecules, leading to potential health risks in living organisms.
##How do normal objects become radioactive?
Normal objects can become radioactive through exposure to radioactive materials or sources. This can happen in various ways, including:
1. Contamination: When radioactive particles or substances come into contact with an object, they can adhere to its surface and make it radioactive.
2. Absorption: Some materials have the ability to absorb radiation and become radioactive themselves. For example, concrete structures near nuclear reactors can absorb radioactivity over time.
3. Induced radioactivity: Certain materials can become radioactive when exposed to high-energy radiation sources, such as X-rays or gamma rays. This process, known as induced radioactivity, can result in temporary or long-lasting radioactivity in objects.
##Examples of normal objects becoming radioactive
There are several examples of normal objects becoming radioactive due to exposure to radioactive materials or sources:
– Clothing: As mentioned in the Chernobyl documentary, clothing can become radioactive if it comes into contact with radioactive dust or particles. This contamination can persist unless the clothing is properly decontaminated.
– Building materials: Concrete, steel, and other building materials used in or around nuclear facilities can absorb radioactivity and become radioactive over time.
– Food and water: Consumables like food and water can become radioactive if they are contaminated by radioactive substances. This poses significant health risks to those who ingest or come into contact with these materials.
##Debunking common misconceptions
There are several misconceptions surrounding radioactivity and its effects on everyday objects. Here are a few common myths debunked:
1. Air and water can become radioactive: Contrary to popular belief, air and water can become radioactive if they are contaminated by radioactive materials. This can happen through airborne particles or waterborne contaminants, leading to widespread radioactivity in the environment.
2. Sealing radioactive objects eliminates radioactivity: While sealing a radioactive object can contain its radiation, the object itself remains radioactive. Radioactivity persists in the sealed object until it undergoes radioactive decay or is properly disposed of.
##Conclusion
In conclusion, normal objects can indeed become radioactive under certain conditions. Understanding how this process occurs and the potential risks associated with radioactivity is crucial for maintaining a safe and healthy environment. By debunking common myths and providing examples, we hope to shed light on this complex topic and emphasize the importance of proper radiation safety measures. Stay informed and stay safe! 🌟

It can happen with neutron radiation. Non-radioactive materials can become radioactive from nuclear reactions. Nuclear reactors have many neutrons flying around in the core which get absorbed by some nuclei. If that is uranium-235 then it’s likely to cause fission – that’s how the reactor works. If that’s regular hydrogen then it becomes deuterium (stable hydrogen is converted to other stable hydrogen), if that’s deuterium it becomes tritium (stable hydrogen is converted to radioactive hydrogen).
Almost all nuclear reactors are water-cooled, so you always produce some tritium in their water. Most other materials get activated to some degree as well.
This is specific to neutron radiation. You don’t see that with other radiation types (with very few exceptions). And you need a running nuclear reactor or a nuclear explosion to make something significantly radioactive.
Particle accelerators can induce nuclear reactions with other particles, too, as their particles can have much higher energies. Some of their components become radioactive over time.
Water and air will only be radioactive for a few minutes if neutron activated.
The graphite in the reactor builds up Carbon-14 with a very long half life, however.
>I saw a chernobyl documentary where they specifically said that it wasnt the particles in the air but the air and water itself that became radioactive….
I wanted to address this specifically. While water can become radioactive if enough of the impurities in water are activated by neutrons, it’ll most likely get dispersed to insignificant levels depending on the size of the body of water. A fun fact about the cooling pools in reactors is that you could technically swim in them while the reactor is active. It’s a bit more convoluted than that when you get more into the details, but the example explains that water is a pretty good shield for radiation.
As for air it’s more likely they were referring to radioactive particles in the air and not the air itself. Radioactive particles are generally very heavy and will get kicked up into the air when disturbed, but eventually settle back down. So it is dangerous to breath these particles in. Something as simple as a cloth mask over your face and covering up as much of your body as possible will generally keep you safe in that situation.
>if your clothes are radioactive it means you have some Uranium dust on it.
Clothes _are_ radioactive. As is nearly everything. It’s just _very_ little radioactivity so it can be ignored. Some objects, like bananas and concrete, store enough of those radioactive atoms that you can measure them over the background that’s everything else.
But to answer your question, yes. Objects can become radioactive from other radioactive objects. Madame Curie’s notebook (and her body) is a cool example. Also steel from before ww2 was less active as steel from after. Some medical equipment’s made from recycled boats from before the war to minimize that influence.
These levels are in most cases non dangerous, unlike themat notebook and eg hospital waste.
Yeah it can but it needs to undergo neutron activation. Basically it needs to be exposed to neutron radiation. I work in nuclear and we have to be wary of certain alloying elements in steels etc. Cobalt is a great example, at the right concentrations in an alloy it can become highly problematic if it becomes cobalt-60.
There are radioactive isotopes of every element. In fact, in spent nuclear fuel, the high-activity elements are usually the fusion products (i.e. the ones that create the decay heat). It trips a lot of people up, but spent fuel is way, way more radioactive than new fuel, even though there’s less uranium-235.
So the many, many radioisotopes created by the fission process can behave in all sorts of chemical reactions. Iodine and radioactive noble gases are of particular concern for airborne contamination because they commonly travel as vapors and gases and have a tendency to spread further than other fission products in a nuclear power disaster. Cesium is highly reactive with water and will be completely dissolved readily, and it will be nearly impossible to filter out.Â
