Medical isotopes are used by medical professionals to diagnose and treat health conditions such as heart disease and cancer. The production of medical isotopes is achieved by using two overarching technologies: nuclear reactors, and particle accelerators (linear accelerators, cyclotrons).


How is phosphorus-32 used in agriculture?

Phosphorus-32 is used in plant sciences for tracking a plant’s uptake of fertiliser from the roots to the leaves. The phosphorus-32-labelled fertiliser is given to the plant hydroponically or via water in the soil and the usage of the phosphorus can be mapped from the emitted beta radiation.


What is food irradiation what isotopes are used?

Food is irradiated with cobalt-60, which decays by beta emission to a nickel isotope. The nickel isotope decays by the gamma emission which is the radiation primarily responsible for killing microorganisms.


How are radioactive isotopes used in industry?

Radioisotopes are used by manufacturers as tracers to monitor fluid flow and filtration, detect leaks, and gauge engine wear and corrosion of process equipment. Small concentrations of short-lived isotopes can be detected whilst no residues remain in the environment.


Why are isotopes important for farmers?

Since the use of isotopes gives the ability to track the amount of fertilizers plants use, this also allows farmers to provide the plants with the right amount of nutrients, promoting maximal crop production.


What is radioisotopes in agriculture?

In agriculture, the elements that plants require can be substituted with radioisotopes of the same element. This allows the usage of the fertilizer to be tracked through the plant’s structure, giving farmers the ability to understand how much fertilizer a plant requires and how much fertilizer is lost to the environment.


How is phosphorus 32 used in plant science?

Phosphorus-32 is used in plant sciences to track the intake of fertilizer from the roots to the leaves. When Phosphorus-32 labeled fertilizer is given to plants through water in the soil, the usage of the phosphorus can be mapped through the emitted beta radiation. With the help of the information gathered from mapping the fertilizer intake, it is easier to understand how a plant takes up and uses the phosphorus from the fertilizer.


What is nitrogen 15?

Nitrogen-15 is a rare stable isotope of nitrogen. In agriculture, botanists use N-15 to track the movement and absorption of fertilizer by plants . When the isotope is mixed into the fertilizer and monitored, botanists are able to understand how effective the fertilizer is with the growth of the plant.


How does radiation affect plant breeding?

Using radiation create mutations in plant breeding produces new genetic lines of different crops.


What is natural abundance?

Natural abundance is the measure of the average amount of a given isotope naturally occurring on Earth.


What is the science of agriculture?

Agriculture is the science or practice of farming, including improving the soil for the growing of crops and the breeding or raising of animals to provide things such as food or wool.


Why are isotopes used in archaeology?

Isotopes are even used in archaeology, the science of humanity and the study of ancient civilizations. Carbon dating is commonly used to determine the age of artifacts and fossil remains. The premise is based on the fact that biological organisms are carbon based life forms. Using this information, carbon decay can be used to age the fossil remains.


Why is radioisotope used in food preservation?

Certain isotopes, called radioisotopes, can be used to help understand chemical and biological processes in plants. In the field of food preservation, food irradiation is used. This process is a method of treating food that makes it safer to eat and makes it have a longer shelf life. This process is not very different from other treatments such as pesticide application, freezing and canning. And, it is effective in eliminating growth of disease- causing or spoilage-causing micro-organisms


What does it mean to be an isotope?

The term isotope is a derived from the Greek words Isos, which means equal, and topos, which means place . An isotope is a variant of a basic element, which has the same atomic number, but has a different atomic mass. While we once thought that every stable atom has an equal number of neutrons and protons, we know now that this is not true. In some elements, the charge remains balance and many may have one more neutron than proton. An isotope is that atom that will not have that same balance.


What is the power of the atom?

The power of the atom is an incredible thing . We know this from the stories of the atomic bomb. So much energy is released with the power to level buildings and destroy lives. However, there is another side to the power. Now, energy from the atom can be harnessed as nuclear power. The isotope, Uranium-235, gets most of the credit for this feat. Through a process caused fusion, rather than fission, power is released and used to power cities.


Who was the first person to use the term “isotope”?

The term isotope was first used by Margaret Todd, the Scottish doctor and cousin of radiochemist and Nobel Prize Winner Frederick Soddy. Working with Nobel Laureate Ernest Rutherford, Soddy, was able to prove that elements transmuted and this is in essence radioactivity. Working to steps to radioactive materials (radium and uranium), Soddy was able to isolates.


Is an isotope stable?

Isotopes can be stable or unstable. Unstable isotopes, or radioisotopes, emit high-energy particles (radiation) which causes them to decay. The decay may cause a chemical atom to lose particles and possible become another isotope or another element all together. Stable isotopes on the other hand, as the name indicates, have become what they will be and no changes will occur to their structures.

What is the objective of fertilizer application?

One of which is that, the objective of the fertilizer application is to supply nutrients to plant not to the soil. Last concern is economical. Costs of fertilizers can be minimized with their optimal application which can save millions of money for a country.


Why is fertilizer balance important?

Therefore, nutrient-fertilizer balance is very necessary and essential to preserve the quality of soil as well as for more agricultural production . Second reason behind optimization of fertilizer application is environmental pollution.


What are the nutrients in fertilizer?

Other nutrients such as Boron (B), Sodium ( Na), Calcium (Ca), Magnesium (Mg),Manganese (Mn), Chloride (Cl), Iron (Fe),Zn (Zinc),Copper (Cu) and Molybdenum (Mo) also need to be added to maintain and induce proper growth and development.
