Radiation refers to the emission of energy in the form of waves or particles, while radioactivity is the property of certain elements to spontaneously emit radiation. Not all radiation is radioactive, but all radioactivity involves radiation.
Both are approaches for a nuclei to reach stability.
Radioactivity is the emission of radiation by the radioactive nuclei in its process to gain stability. This radiation could Alpha particles, beta particles (negative or positive), gamma electromagnetic radiation, neutrons, ect.
Fissionability is the splitting of a nuclide into two (rarely three) smaller nuclei plus other small particles as neutrons. This fission could be spontaneous fission or an induced fission (induced by e.g. neutron bombardment)
Radioactivity is the general property common to all radioactive materials. Radioactive is a qualifierused to identify materials having this general property.
Examples:
- The radioactivity of the sample was unusually high.
- Radioactive Carbon-14 levels in charcoal or bone can be used to determine age.

What is property in which unstable nuclei of an element spontaneously emit radiation?
Radioactivity is the property in which unstable nuclei of an element spontaneously emit radiation.
What are the types of radiactivity?
The three main types of radioactivity are alpha radiation, beta radiation, and gamma radiation. Alpha radiation consists of helium nuclei, while beta radiation consists of electrons or positrons. Gamma radiation is a high-energy form of electromagnetic radiation.
Will doubling the source of radioactivity halve the radiation intensity?
No, doubling the source of radioactivity will not halve the radiation intensity. Radiation intensity is directly proportional to the amount of radioactive material present. So doubling the source will double the radiation intensity.
Why is radioactivity hazardous?
Radioactivity is hazardous because it emits ionizing radiation that can damage living cells and tissues, leading to health problems such as cancer, genetic mutations, and radiation sickness. Exposure to high levels of radioactivity can have serious and long-lasting effects on humans and the environment.
What term is defined as the emission of energy from subatomic particles?
Radioactivity is the term defined as the emission of energy from subatomic particles.
Is there a difference between radioactivity and radioisotopes?
Yes, there is a difference. Radioactivity refers to the property of certain elements to emit radiation, while radioisotopes are versions of elements that have an unstable nucleus and emit radiation as they decay. Radioactivity is a general phenomenon, while radioisotopes are specific isotopes of elements that exhibit this property.
What is radioactivity and what is the difference between alpha beta and gamma radiation?
Alpha radiation is helium-4 nuclei - i.e., each alpha particle consists of 2 protons and 2 neutrons.Beta radiation is either electrons or positrons (= anti-electrons). Gamma radiation is high-energy photons.
What is property in which unstable nuclei of an element spontaneously emit radiation?
Radioactivity is the property in which unstable nuclei of an element spontaneously emit radiation.
What is the difference between thermal and radioactive radiation?
There is no difference
What type of radiation does radioactivity produces?
The Type Of Radiation That It Produce Is The Gamma Ray!
What are the types of radiactivity?
The three main types of radioactivity are alpha radiation, beta radiation, and gamma radiation. Alpha radiation consists of helium nuclei, while beta radiation consists of electrons or positrons. Gamma radiation is a high-energy form of electromagnetic radiation.
What is a sentence for radioactivity?
Radioactivity is the emission of radiation from an unstable atomic nucleus.
Will doubling the source of radioactivity halve the radiation intensity?
No, doubling the source of radioactivity will not halve the radiation intensity. Radiation intensity is directly proportional to the amount of radioactive material present. So doubling the source will double the radiation intensity.
What is a radioactivity substances?
Substances that emit ionizing radiation
What is a fast moving electron that is given off as a nuclear radiation?
Beta radioactivity radiation.
Process which unstable nuclei emit radiation is called?
This process through which unstable nuclei emit radiation is called radioactive decay. It also is called nuclear decay, and it is a natural process in which an atom of an isotope decomposes into a new element.
What is the spontaneous disintegration in which particles or electromagnetic radiation are emitted?
Radioactivity
