The radioactivity of radium then must be enormous. This substance is the most radioactive natural element, a million times more so than uranium.Dec 19, 2018
What item has the most radiation?
Brazil nuts are probably the most radioactive food you can eat. They provide 5,600 pCi/kg (picocuries per kilogram) of potassium-40 and a whopping 1,000-7,000 pCi/kg of radium-226. Although the radium is not retained by the body for very long, the nuts are approximately 1,000 times more radioactive than other foods.
What are the 3 most radioactive elements?
Each element is followed by the most stable known isotope and its half-life. Note increasing atomic number doesn't necessarily make an atom more unstable….Radioactive Elements.
| Element | Most Stable Isotope | Half-life of Most Stable Isotope |
|---|---|---|
| Astatine | At-210 | 8.1 hours |
| Radon | Rn-222 | 3.82 days |
| Francium | Fr-223 | 22 minutes |
| Radium | Ra-226 | 1600 years |

Which group is the most radioactive?
Answer and Explanation: Most radioactive elements are located in the f-block, also known as the inner transition metals (B), which consist of lanthanides and actinides.
What type of materials are radioactive?
Radionuclides (radioactive materials)
- Cesium.
- Cobalt.
- Iodine.
- Ionizing Radiation.
- Plutonium.
- Radium.
- Radon.

Can we buy uranium?
Yet, the truth is, you can buy uranium ore from places like Amazon or Ebay, and you won't have to produce any special authorization to get it. The purpose of buying Uranium-238, the most common isotope of the element, is purely for research.
Can you buy radioactive material?
Ordering Licensed Radioactive Materials For common vendors such as Perkin-Elmer or MP Biomedical, place an order through the PRIME Marketplace. The radioactive items you order through the Marketplace are coded by default as Radioactive, and the req will be routed to EHS for approval.
Can you buy polonium?
Yes, Polonium-210, "which experts say is many times more deadly than cyanide," the story notes, "can be bought legally through United Nuclear Scientific Supplies, a mail-order company that sells through the Web.
What is polonium used for?
Polonium is an alpha-emitter, and is used as an alpha-particle source in the form of a thin film on a stainless steel disc. These are used in antistatic devices and for research purposes. A single gram of polonium will reach a temperature of 500°C as a result of the alpha radiation emitted.
Can you buy radium?
The majority of people cannot buy radium. As a consequence, we recommend only qualified buyers in order to obtain radium. A regular person is not generally able to buy radium.
