What else can I help you with?
What happens to all radioactive isotopes?
All radioactive isotopes will disintegrate.
What happens to a region when radioactive particles are released?
This region become a radioactive contaminated area.
What are the three primary ways radioactive isotopes can enter the body?
Radioactive isotopes can enter the body primarily through inhalation, ingestion, and absorption through the skin. Inhalation occurs when radioactive particles are breathed in, often from contaminated air. Ingestion happens when radioactive materials are consumed through food, water, or contaminated surfaces. Absorption can occur when radioactive substances come into contact with the skin or through wounds.
Which describes what happens during a chain reaction?
Neutrons released during a fission reaction trigger other fission reactions.
What happens when you mix radium with water?
When radium comes into contact with water, it reacts to form radium hydroxide and hydrogen gas. Radium is a highly radioactive element, so caution should be taken to avoid exposure to both the radioactive material and the chemical reaction byproducts.

Do radioactive isotopes disintegrate easily?
There is a very wide range of half-life for different radioactive isotopes, ranging from the billions of years to very small fractions of a second. So some isotopes disintegrate immediately, and others last a very long time.

What happens to atoms that are radioactive?
Radioactive atoms undergo spontaneous decay, emitting particles or energy in the form of radiation. This process transforms the atoms into different elements or isotopes, creating new elements that may also be radioactive. This decay continues until the atom reaches a stable state.
What chemical reaction happens when a hydrocarbon burns?
The reaction is called oxidation; carbon dioxide and water are released.
Does nuclear radiation go away?
No, it doesn't.Wrong, it does. There are 2 types of nuclear radiation: prompt & decay.Prompt nuclear radiation occurs for a period of time while the reaction that generates it is happening. Examples are the flash of neutrons, light, x-rays, etc. when a nuclear bomb explodes as well as the sustained neutron flux as a nuclear reactor is in operation. When the reaction stops, prompt nuclear radiation goes away.Decay nuclear radiation occurs as radioactive isotopes decay to different isotopes. As the decay happens (which is a probabilistic process) the radioactive isotope is consumed. This follows an exponential function with one half of the current amount of the radioactive isotope consumed in each period of time called a halflife. While there will always be a tiny residue of the original radioactive isotope, for practical purposes it is considered to be negligible after 5 halflives have passed. When 5 halflives of the radioactive isotope decaying have passed, decay nuclear radiation is considered to have gone away for practical purposes.
How do radioisotopes of an element differ feom other isotopes?
Radioisotopes are "radioactive isotopes"; they are not stable. Radioactive atoms will decay, or break apart into other atoms, by emitting an electron, or a neutron or a positron or an alpha particle (2 protons and two neutrons). The rate at which this happens is measured by the "half-life"; after one half-life, half of the atoms will have decayed. After another half-life, half of the remaining atoms will have decayed. Atoms with short half-lives are highly radioactive, and can be fairly dangerous. Atoms with long half-lives are only slightly radioactive, and aren't all that dangerous.

What happens to the heat when an exergonic reaction occurs in living cells?
It's being released.
What happens to energy in an exothermic reaction?
It is released into whatever medium is there to take it - air, for instance.
