What does water do in radiation shielding and does it work as an absorber of neutrons?
H2O provides an energy transfer for radiant energy. The volume of H2O per radiant energy is proportional. The visual energy transfer may be measured by H2O's "change of state" rate.
Regarding H20 as an absorber of electrons, oxygen has a larger share of electrons. This is how one Oxygen atom and two Hydrogen atoms bond to create H2O. See "polar covalent bond" and "electronegativity" for greater depth.
If a flux of electrons bombard H2O, the molecular compound will change in composition -OR- reform in an entirely different molecular compound.
What else can I help you with?
How can nuclear radiation be absorbed?
Yes. Any element which is radioactive may bond together with other molecules and atoms, just as much as any other non-radioactive element. However, radioactive elements would have a slightly greater pull towards their bonded species if their nucleus has more neutrons than what is normal for non-radioactive elements.
How different materials can be used to decrease radiation?
Materials such as lead, concrete, and water can be used to decrease radiation exposure by acting as shields that absorb or block the radiation. Lead is commonly used due to its high density and ability to absorb radiation. Concrete is effective for shielding against gamma rays, and water can be used as a shield for certain types of radiation due to its hydrogen atoms absorbing and scattering radiation.
Why did they add boron to water to dump on the nuclear reactor?
Boron is a good absorber of neutrons and would be useful in preventing criticality, if the fuel had melted and was possibly going to form a critical mass. I don't know how likely this was, but it seems more of a precaution than a real necessity, at present anyway.
Does reverse osmosis effectively remove radiation from water?
Yes, reverse osmosis is an effective method for removing radiation from water.
How many neutrons are in water?
In a single molecule of water : 10 protons (1 from each hydrogen and 8 from oxygen)8 neutrons (none from hydrogen and 8 from oxygen)water = H2O 10 electrons (1 from each hydrogen and 8 from oxygen)To work out how many electrons, protons and neutrons in a molecule;Find the ballenced chemical equation - H20 in this caseLook up each element in the periodic table - hydrogen and oxygen in this caseCount the electrons, protons and neutrons - you do this by looking at the top numbers and the bottom numbers for each element. The top number is the "atomic weight" of the element, so the total number of protons and neutrons as each 1 unit of mass. The bottom number is the "proton number" number of electrons and protons (each) so for oxygen where the number is 8, there are 8 protons and 8 electrons. To work out the number of neutrons simply take the bottom number from the top number as you are taking the number of protons away from the total weight to give you whats left, which is the number of protons.Do a little bit more adding - H2O = 2 + 8 electrons= 2 + 8 protons= 0 + 8 neutronsAnd your done. Easy
Why are carbon dioxide and water vapor called selective absorbers?
Any object that can specifically absorb and emit radiation (in the form of, say, infrared radiation), is called a selective absorbers. An example is: Snow. It is a good absorber of infrared radiation but poor absorber of sunligh. Object that selectively absorb radiation at some wavelength tend to radiate radiation at that same wavelength. CO2 and water vapors are both very good absorber of infrared radiation but at the same time poor absorber of different forms of solar radiation that are visible to us.
Why does the moon not support life?
Because it has no air, no water, no shielding from space radiation, and no pizza there.
Which greenhouse gas is the most powerful absorber radiation emitted by earth?
Carbon dioxide (CO2) is the most powerful absorber of longwave radiation emitted by Earth, leading to the greenhouse effect and global warming.
Why the distance shielding for Gamma ray and Emitted Neturon is different?
Gamma rays are a form of electromagnetic radiation, and are absorbed by heavy materials such as lead which is often used for such shielding. Neutrons are uncharged particles which can pass through many materials, but are strongly absorbed by for example cadmium and boron, which are said to have a high capture cross section for neutrons. Therefore effective neutron shields can use such materials.
What is the best absorber infra-red radiation?
Carbon dioxide is one of the best absorbers of infrared radiation in Earth's atmosphere. Water vapor is another important absorber of infrared radiation. Both of these gases contribute to Earth's greenhouse effect, trapping heat and helping to regulate the planet's temperature.
What is best absorber of infrared radiation?
well, i believe Co2 (carbon dioxide) and H2o (water) are the best absorbers of infrared radiation my young grass hopper. Beast
What is a radiation stopped by?
Radiation can be stopped or attenuated by materials such as lead, concrete, water, or even air. The effectiveness of the barrier depends on the type of radiation, its energy level, and the thickness of the shielding material.
What element used as shield for radioactivity?
It depends somewhat on the type of radiation that one needs to be shielded.Lead is very effective for gamma rays, however if the radiation is mostly neutron radiation then borated reinforced concrete is much more effective than lead (the hydrogen in the water of crystallization in the concrete slows the neutrons and the boron then absorbs the slow neutrons). Nuclear reactors which produce intense radiation of both gamma ray and neutron often use alternating layers of lead plate and borated reinforced concrete for shielding.If all you are shielding against is beta radiation then a sheet of aluminum foil is typically adequate.If all you are shielding against is alpha radiation then your skin (do not ingest or inhale alpha emitters) or one sheet of paper is adequate.
How is chain reaction controlled in a nuclear power plant?
The radiation shield used on a large scale for fixed shielding is concrete. This is effective because the large mass of concrete absorbs gamma radiation well, and as it contains a lot of water molecules it also stops neutrons from penetrating.
Which greenhouse gas is the most powerful absorber of radiation emitted by Earth?
Carbon dioxide (CO2) is the most powerful absorber of radiation emitted by Earth among greenhouse gases. It contributes significantly to the greenhouse effect and plays a key role in regulating Earth's temperature.
What Materials that can absorb radiation?
Materials that can absorb radiation include lead, concrete, and water. Lead is commonly used in shielding for its dense properties, concrete provides effective radiation protection due to its thickness and density, and water can act as a shield against certain types of radiation.
What is shielding in a nuclear reactor?
Shielding is the use of materials to absorb free or loose radiation, and prevent it from leaving the reactor; this would be a hazard to workers otherwise. The standard materials are concrete and lead, for their ease of use and installment, low cost and high effectiveness.
