What are radioactive element and examples?
Radioactive Elements
| Element | Most Stable Isotope | Half-life of Most Stable Isotope |
|---|---|---|
| Actinium | Ac-227 | 21.77 years |
| Thorium | Th-229 | 7.54 x 104 years |
| Protactinium | Pa-231 | 3.28 x 104 years |
| Uranium | U-236 | 2.34 x 107 years |
What is the first radioactive element?
While uranium was the first radioactive element to be discovered, radium was much more popular, as it was a spontaneously luminous material that emitted an incredible quantity of radiation.
Are potatoes radioactive?
Potatoes. As with carrots, white potatoes offer between 1 and 2.5 pCi/kilogram of radon-226 and 3,400 pCi/kilogram of potassium-40. Foods made from potatoes, such as chips and french fries, are similarly slightly radioactive.
Which is an example of a radioactive element?
A good example of this is tritium, a radioactive isotope of hydrogen naturally present at extremely low levels. This table contains the elements that have no stable isotopes. 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.
Are there any everyday products that are radioactive?
10 Radioactive Everyday Products. 1 Brazil Nuts Are Radioactive. Jennifer Levy/Getty Images. 2 Beer Is Radioactive. 3 Kitty Litter Is Radioactive. 4 Bananas Are Naturally Radioactive. 5 Radioactive Smoke Detectors.
Are there any gemstones that are naturally radioactive?
The radioactive isotope is not a concern unless the bulb is broken. Even then, the toxicity of other chemicals typically outweighs any risk from radioactivity. Some gemstones, such as zircon, are naturally radioactive. Additionally, several gemstones may be irradiated with neutrons to enhance their color.
