Is chlorine 36 stable?

Chlorine-36 is an unstable isotope of chlorine produced by cosmic-ray bombardment of the atmosphere and the Earth’s surface as well as by absorption of cosmic-ray or natural radioactivity-derived neutrons in stable chlorine.

Is chlorine 36 man made or natural?

It is produced naturally by atmospheric photochemical reactions, and also is synthesized in large quantities for military, aerospace, and industrial applications.

Is chlorine 37 radioactive?

There are two stable isotopes, 35Cl (75.77%) and 37Cl (24.23%), giving chlorine a standard atomic weight of 35.45. The longest-lived radioactive isotope is 36Cl, which has a half-life of 301,000 years….List of isotopes.

How common is chlorine 36?

Chlorine has two stable isotopes and one naturally occurring radioactive isotope, the cosmogenic isotope 36Cl. Its half-life is 301,300 ± 1,500 years. Cl decays primarily (98%) by beta-minus decay to 36Ar, and the balance to 36S….Chlorine-36.

What is the percent abundance of chlorine-35?

75%
Chlorine naturally exists as two isotopes, 17 35 Cl (chlorine-35) and 17 37 Cl (chlorine-37). The abundance of chlorine-35 is 75% and the abundance of chlorine-37 is 25%. In other words, in every 100 chlorine atoms, 75 atoms have a mass number of 35, and 25 atoms have a mass number of 37.

What is the difference between chlorine-35 and chlorine-37?

Chlorine-35 and chlorine-37 are both isotopes of the element chlorine. An atom of chlorine-35 contains 18 neutrons (17 protons + 18 neutrons = 35 particles in the nucleus) while an atom of chlorine-37 contains 20 neutrons (17 protons + 20 neutrons = 37 particles in the nucleus).

What is the percent abundance of chlorine 35?

Where is chlorine-36 found?

the atmosphere
Chlorine-36 is produced in the atmosphere by cosmic-ray spallation of 40Ar (Lal and Peters, 1967). It decays to 36Ar with a half-life of 301 000 ± 4000 years (Bentley et al., 1986a).

What is chlorine-35 used for?

Both Chlorine isotopes, Cl-35 and Cl-37, are used to study the toxicity of environmental pollutant and are usually supplied in the form of NaCl.

Why is chlorine 36 used?

Chlorine-36 has been widely used for dating old groundwater. The 36Cl used for this purpose is produced in the atmosphere by the interaction of cosmic rays with argon atoms. Groundwater recharge carries the 36Cl into the subsurface where the radiometric “clock” is set.

What is the abundance of chlorine-37?

25%

What percentage of natural chlorine is chlorine-37?

24.23%
Chlorine-37 accounts for 24.23% of natural chlorine, chlorine-35 accounting for 75.77%, giving chlorine atoms in bulk an apparent atomic weight of 35.453(2) g/mol.

What is chlorine-36 chloride?

Chorine as chloride is an essential nutrient in the human diet and is necessary for healthy nervous and digestive systems. Once taken in, chlorine-36 behaves in the body in the same manner as other chlorine isotopes.

What happens if you are exposed to chlorine?

Exposure to low levels of chlorine can result in nose, throat, and eye irritation. At higher levels, breathing chlorine gas may result in changes in breathing rate and coughing, and damage to the lungs. Additional symptoms of exposure to chlorine can be severe. Workers may be harmed from exposure to chlorine.

Is chlorine harmful to workers?

Workers may be harmed from exposure to chlorine. The level of exposure depends upon the dose, duration, and work being done. Chlorine is used in many industries. It’s used in the pulp and paper industries, pool chemical products, cleaning products, mining products, bleach and plastics manufacturing.

Is there gamma radiation from chlorine 36?

External gamma exposure is not a concern because chlorine-36 decays by emitting a relatively low-energy beta particle with only a small amount of gamma radiation. While in the body, chlorine presents a health hazard from the beta particles and gamma radiation.
