How are isotopes being used in agriculture?
In agriculture, radiation and radioisotopes are also used in the nutritional studies of trace elements, mechanism of photosynthesis, plant protection including action of insecticides, metabolisms in plant, uptake of fertilizers, ions mobility in soils and plants and food preservation.
What is radioactivity What are the applications of radioisotopes?
Radioactive isotopes have many useful applications. In medicine, for example, cobalt-60 is extensively employed as a radiation source to arrest the development of cancer. Other radioactive isotopes are used as tracers for diagnostic purposes as well as in research on metabolic processes.
What are the uses of electromagnetic radiation in agriculture?
Electromagnetic waves as tools in the field of agriculture have been used in many applications such as remote sensing, imaging, quality sensing, and dielectric heating in a pre-harvest or post-harvest environment.
Which radioactive isotope is used for food preservation?
The two most common sources of high-energy radiation used in the food industry are cobalt-60 (60Co) and cesium-137 (137Cs). For the same level of energy, gamma rays have a greater penetrating power into foods than high-speed electrons.
What is the application of radioactivity?
Uses of radioactivity Medical use: Many diseases such as cancer are cured by radio therapy. Sterilization of medical instruments and food is another common application of radiation. 2. Scientific use: Alpha particles emitted from the radio isotopes are used for nuclear reactions.
What are some applications of radioactivity?
Uses of radioactivity
- Medical use: Many diseases such as cancer are cured by radio therapy.
- Scientific use: Alpha particles emitted from the radio isotopes are used for nuclear reactions.

What are some common applications of radioactivity?
Today, to benefit humankind, radiation is used in medicine, academics, and industry, as well as for generating electricity. In addition, radiation has useful applications in such areas as agriculture, archaeology (carbon dating), space exploration, law enforcement, geology (including mining), and many others.
What is electromagnetic radiation in food?
Microwave and radio frequency energy are portions of the electromagnetic spectrum that can deliver heat to foods selectively and efficiently. Specifically, microwaves interact with water in foods to heat predominantly those portions that are wet.
Which waves are used for pest control?
Ultrasonic. Ultrasonic devices operate through emitting short wavelength, high frequency sound waves that are too high in pitch to be heard by the human ear (generally accepted to be frequencies greater than 20,000 Hz).
What are some of the application of radioactivity in food technology?
Food irradiation (the application of ionizing radiation to food) is a technology that improves the safety and extends the shelf life of foods by reducing or eliminating microorganisms and insects. Like pasteurizing milk and canning fruits and vegetables, irradiation can make food safer for the consumer.
How can radioactivity be used to preserve food?
To preserve food with radiation, the item is exposed to to gamma rays (which are similar to X-rays) emitted by radioactive materials. The radiation destroys food-borne bacteria. Radiation is measured in units called rads. The FDA allows exposure of up to 100,000 rads for already approved foods.
What are the most common applications of isotopes in daily life activities?
Among such prevalent uses and applications of radioisotopes are, in smoke detectors; to detect flaws in steel sections used for bridge and jet airliner construction; to check the integrities of welds on pipes (such as the Alaska pipeline), tanks, and structures such as jet engines; in equipment used to gauge thickness …
What are the uses of electromagnetic radiation in agriculture and organism?
iNtRoduCTIoN. Electromagnetic waves as tools in the field of agriculture have been used in many applications such as remote sensing, imaging, quality sensing, and dielectric heating in a pre-harvest or post-harvest environment.
Which part of electromagnetic wave is used for preservation of food?
Microwaves and Radiowaves: In Food Processing and Preservation.
How are radioisotopes used in agriculture?
In agricultural applications, application of radioisotopes in agriculture pdf download Radioactive isotopes or radioisotopes are used as the source of radiation. An advantage of fission reactors is that they can be used to produce radioactive isotopes for a number of special applications.
What are the applications of radioactive tracers in agriculture?
Some of the most interesting and valuable applications of radioactive tracers have radioactive tracers in agriculture. 5. the application of radioactive In agricultural applications, radioisotopes are usually used as tracers. In addition, radiation can be used to exterminate insects.
What are radioisotopes and why are they important?
Radioisotopes and radiation used in food and agriculture are helping to reduce these figures. The attributes of naturally decaying atoms, known as radioisotopes, give rise to their multiple applications across many aspects of modern day life (see also information page on The Many Uses of Nuclear Technology ).
