What does calcium radioactive decay into?
What does calcium radioactive decay into?
It decays by β- decay to 40Ca and to 40Ar by both electron capture and positron decay (see Potassium-argon decay system). Although 89.52% of the decays produce 40Ca, the system is of somewhat limited use due to the large natural abundance of 40Ca (96.9% of calcium, see Calcium).
What element does Ca 37 decay into?
List of isotopes
| Nuclide | Z | Decay mode |
|---|---|---|
| 37Ca | 20 | β+, p (82.1%) |
| β+ (17.9%) | ||
| 38Ca | 20 | β+ |
What is the beta decay of calcium?
Although it is unusually neutron-rich for such a light nucleus, its beta decay is extremely hindered, and so the only radioactive decay pathway that it has been observed to undergo is the extremely rare process of double beta decay….Calcium-48.

Is calcium a radioactive?
Calcium has six stable isotopes, two of which occur in nature: stable 40Ca and radioactive 41Ca with a half-life = 106 years.
What are uses of calcium?
Calcium is also used in the production of some metals, as an allying agent. Calcium carbonate is used to make cement and mortar and also in the glass industry. alcium carbonate is also added to toothpaste and mineral supplements. Calcium carbide is used to make plastics and to make acetylene gas.
What is the characteristics of calcium?
Calcium is a silvery-white, soft metal that tarnishes rapidly in air and reacts with water. Calcium metal is used as a reducing agent in preparing other metals such as thorium and uranium. It is also used as an alloying agent for aluminium, beryllium, copper, lead and magnesium alloys.
Is calcium 39 an isotope?
Atoms which have the same atomic number but different mass numbers are isotopes. For example, all calcium atoms have an atomic number of 20 but there are three isotopes of calcium – 39, 40, and 42.
Is uranium 238 stable?
Uranium’s most stable isotope, uranium-238, has a half-life of about 4,468,000,000 years. It decays into thorium-234 through alpha decay or decays through spontaneous fission. Uranium-238 is not fissile, but is a fertile isotope, because after neutron activation it can produce plutonium-239, another fissile isotope.
What kind of radioactive decay will calcium 45 most likely undergo?
alpha decay
Calcium-45 undergoes alpha decay.
What type of radiation does calcium 47 emit?
gamma ray
Radioactive calcium 47 has a half-life of 4.7 days and emits a high-energy gamma ray of 1.3 Mev as well as a beta particle in its decay to scandium 47.
Is calcium toxic?
Can calcium be harmful? Some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer.
