How is radioactivity used in agriculture?
The increase in the volume and quality of grains and cereals has been vastly improved by selectively growing superior strains labeled by radioactive isotopes. These improvements are helping to alleviate famine in third world countries.
Does hafnium have a smell?
The element hafnium has no distinctive odor, nor is it magnetic at room temperature. There are five stable isotopes of this element, so most hafnium is not radioactive. But there are a number of isotopes that have been synthesized that are radioisotopes. Additionally, this transition metal is not explosive or even flammable. A link can be found below.
Is there a list of radioactive elements?
Yes, there is. In fact, there are several lists. See, the thing is that some elements are radioactive "across the board" like uranium is. All of the different isotopes of uranium are radioactive. But some elements have several isotopes that are stable, and some that are radioactive, or a "mixed bag" if you will. Just getting a "list" per se might be a mess. How are you going to list all those radioactive isotopes of all those elements? Well, there's good news. The table of nuclides (or table of radionuclides) has all the elements and all their isotopes. It's a pretty good sized table, to be sure, but it's been around and is available on the web in a number of places. One is from the Brookhaven National Laboratory's site for the National Nuclear Data Center. A link is provided to that one. Note that each little "square" on the chart is "active" and clicking on it pulls up the data on that isotope, whatever it is. There are other tools for use to extract data from the chart. Short cut If you just want to know which elements have no stable isotopes and which, therefore, are radioactive in any form, they include 43technetium and 61promethium, and all elements above 83bismuth. Simple and easy.
What are the names of the isotopes of thorium?
Copper (used in the treatment of cancer), Iodine (used in diagnostics) and 14C (used in radioactive dating/carbon dating)
What is element 106?
An artificially produced radioactive element with atomic number 106 that has only been produced in trace amounts. The isotope with mass number 266 has the longest confirmed half-life (21 seconds), although heavier isotopes with longer half-lives have been reported.
Does Barium have isotopes that are all radioactive?
Usually not, but all elements have radioactive isotopes.

How do scientistes determine how meteorites been have in space?
By looking at radioactive isotopes. These isotopes decay at precisely known rates, so looking at ratios involving such isotopes can tell when an asteroid or other object formed.
Radioactive dating of rock samples is a method?
used to determine the age of rocks and minerals by measuring the abundance of certain radioactive isotopes within them. This method relies on the fact that radioactive isotopes decay at a known rate over time. By measuring the ratio of parent isotopes to daughter isotopes, scientists can calculate how long it has been since the rock or mineral formed.

How have the amounts of Earth's radioactive isotopes changed over time and why has it changed?
They have been slowly declining over time because they decay, eventually becoming stable isotopes of other elements.

Is phosphorescence radioactive?
Ordinary phosphorus found in nature is not radioactive. Like all other elements, radioactive synthetic isotopes of phosphorus have been made.
