What is borated concrete?
The borated concrete that is being used in ITER is a high-density concrete (3.7 tonnes per cubic metre as compared to 2.4 tonnes for a standard formulation) that includes 0.3 percent of boron. The neutron-eating element is obtained from ground colemanite aggregates, a borate mineral that is imported from Turkey.
What is borated polyethylene?
Borated HDPE (High density polyethylene) is a product specially designed for nuclear shielding applications. The material employs 5% Boron by weight to shield neutrons in a variety of applications including high intensity X-rays, cancer treatment facilities, hospitals, nuclear submarines and nuclear power plants.
What does the word borated mean?
Definition of borated : mixed or impregnated with borax or boric acid.
What is neutron shielding?
Shielding ionizing radiation means having some material between the source of radiation and you (or some device) that will absorb the radiation. Neutrons must be slowed down and then absorbed to shield neutron radiation.
What is the use of sodium borate?
Borax is a powdery white substance, also known as sodium borate, sodium tetraborate, or disodium tetraborate. It’s widely used as a household cleaner and a booster for laundry detergent. It’s a combination of boron, sodium, and oxygen.
What is borate formula?
Borate | BO3-3 – PubChem.
Which material is the best for shielding neutron radiation?
Common Neutron Shielding Materials Borated polyethylene, layers of B4C and aluminum, boron-aluminum alloys, and boric acid in water are examples of materials incorporating boron. Adding boron to neutron shielding materials reduces the dose from secondary gamma production from radiative capture (n,γ).
What is the best shield for neutron radiation?
Neutrons readily pass through most material, and hence the absorbed dose (measured in Grays) from a given amount of radiation is low, but interact enough to cause biological damage. The most effective shielding materials are water, or hydrocarbons like polyethylene or paraffin wax.
What is the formula for borate?
What is the formula of sodium borate?
Na₂[B₄O₅(OH)₄]·8H₂OBorax / Formula
What is borate made of?
What Is Borax? Borax is a powdery white substance, also known as sodium borate, sodium tetraborate, or disodium tetraborate. It’s widely used as a household cleaner and a booster for laundry detergent. It’s a combination of boron, sodium, and oxygen.
What chemicals are in borate?
Borates are chemical compounds containing borate anions, that is, anions composed of boron and oxygen. There are various borate ions, the simplest of which is BO33−. These borate anions form salts with metallic elements.
