This effect is used for quantitative measurement of radioactivity. Radioactive wastes cause pollution the high-level products of nuclear wastes remain in the environment for hundreds of years leakage and nuclear reactors also cause large-scale environmental pollution the leakage might lead to several deaths.

These materials are used in the production of nuclear weapons nuclear fuel and electric power.


All organisms are affected by radioactive pollution prolonged and frequent exposure to radioactive substances can cause cancer and leukemia and induce mutations.

Nuclear techniques are increasingly used in industry and environmental management. The radiations cause a number of molecules of the gas radiactividad artificial yahoo dating lose electrons and pass into positive ions. Radioactivity Detector This is the most important factor need to know.

The emission of rays and subatomic particles from the nuclei of certain elements decaying into others, notably uranium and its decay products, down to, but excluding, lead.

Due to ionization, a flow of current occurs, which is measured after amplification. This was discovered by Irene Curie and F. Radioactive rays possessing high-energy jaguar xk review uk dating air, ar dehe, and soil.

The radioactive material used in atom bombs is very destructive the impact of radioactivity on man and environment. Geiger-Muller counter is based on this effect.

Spontaneous emission of radiation, either directly from unstable atomic nuclei or as a consequence of a nuclear reaction.

These males are usually released to mate with females which produce unfertilized eggs. Some of the intermediate stages include the heavier elements thorium, radium, radon, and polonium.

The rate of production of these ions is proportional to the intensity of radiation. This is effective pest control as it reduces the population of insects. A different isotope of sodium is injected into the limb and its flow rate in the body is studied.

Gamma sterilization is used for medical supplies some bulk commodities and increasingly for food preservation. Radiations produce ionization in the gases through which they are passed.

Radioactivity from nuclear bombs and installations, and even certain rocks, can injure living tissues. Example of artificial Radioactive: The rapid response of nuclear techniques results in reduced cost with increased product quality.

The apparatus used for this purpose is called electroscope. O The process in which a stable isotope is converted into a radioactive element by artificial transmutation is called artificial radioactivity. The spontaneous disintegration of certain isotopes accompanied by the emission of radiation a-rays, b-rays, c-rays.

Effects of Radioactivity Radioactive pollution is naturally occurring or artificially produced radioactive materials. Within the nuclei of stable atoms, such as those of lead, the force binding the protons and neutrons to each other individually is great enough to hold the nuclei together as a whole.

Radioactivity - definition of radioactivity by The Free Dictionary

The total ions of one sign are equal to the total ions of the other type. The electrons immediately become attached to the neutral molecules, thus making them negative ions. A short-lived radioactive material is used in flow tracing and mixing measurements in a nuclear plant.

Radioactive sodium is used to detect a clot in the human body. The property of disintegration of a radioactive material is independent of temperature, pressure and other external conditions.

All known elements with an atomic number greater than 83 bismuth are radioactive, and many isotopes of elements with lower atomic numbers are radioactive too. The extent, to which a definite quantity of a gas is rendered a conductor by a radioactive substance, is a measure of the radioactive power of a radioactive substance.


In the nuclei of other atoms, especially of heavy ones such as uranium atoms, this energy is not great enough, and the nuclei are unstable. When enough particles and energy have been given off to create a new, stable nucleus often the nucleus of an entirely different elementthe radioactivity ceases.

It is used to confer high resistance to pests and disease early maturing improved productivity high nutritional value climate resistance adaptation etc. An unstable nucleus gives off particles and energy in a process known as radioactivity.

Another agricultural use of radioisotopes is the genetic modification of plants and animals. Terrestrial radiations from natural Radio isotopes originate from the use of radioactive materials.

Natural Radioactivity All heavy elements from bismuth through uranium and a few of lighter elements have naturally occurring isotopes which possess the property of radioactivity.

Artificial Radioactivity The phenomena by which even light elements are made radioactive by artificial or induce method is called as artificial radioactivity. The various experiments confirmed that the phenomenon of radioactivity does not depend on the orbital electrons but depends only on the composition of a nucleus.

The radiation, including alpha particles, nucleons, electrons, and gamma rays, emitted by a radioactive substance. The mutated genes can persist in human animal and plant populations.

For example, uraniuma very unstable element, goes through 18 different stages of decay before finally turning into a stable isotope of lead, lead The emission of subatomic particles and rays due to the disintegration of the atomic nuclei of certain isotopes of some elements.

Radioactive cobalt due to its gamma radiation is used to treat cancer and kill cancer cells The functioning of thyroid can be studied by iodine isotope. Sealed radioactive sources are used in industrial radiography gauging applications and mineral analysis.

Agriculture radiation is also used in agriculture to sterilize male pupae an insect that could damage crops. These isotopes have unstable nuclei and attain stability through the phenomenon of radioactivity.
