Transcript of radioactive pollution

radioactive pollution
It includes the radioactive elements like radium, uranium, thorium, radon, potassium and carbon. These occur in the rock, soil and water. The man made radiations include the mining and refining of plutonium and thorium. This production and explosion of nuclear weapons include the nuclear fuels, power plants and radioactive isotopes
what is radioactive & light pollution?
Radioactive pollution refers to the contamination and degradation of the environment through nuclear waste. It is the physical pollution of air, water and land through nuclear materials. Radioactive materials that cause pollution may be materials from commercial or laboratory processes.
The radioactive pollution is defined as the physical pollution of air, water and the other radioactive materials. The ability of certain materials to emit the proton, gamma rays and electrons by their nuclei is known as the radioactivity. The protons are known as the alpha particle and the electrons are also known as the beta particle. Those materials are known as the radioactive elements. The environmental radiations can be from different sources and can be natural or manmade.

The radioactive elements are produced in the environment and affect other materials also. It includes the strontium, radium and iodine. The gases and particles are produced by the radioactive materials. They are carried by the wind and the rain brings down the radioactive particles to the ground which is referred as nuclear fallout.

The radioactive elements are produced in the environment and affect other materials also. It includes the strontium, radium and iodine. The gases and particles are produced by the radioactive materials. They are carried by the wind and the rain brings down the radioactive particles to the ground which is referred as nuclear fallout. The soil transfers these radioactive substances to the plants and ultimately they reach the human body and cause many side effects. The iodine may affect the white blood cells, bone marrow, spleen, lymph, skin cancer, sterility, eye and damage to the lung. The strontium has the ability to aggregate in the bones and form a bone cancer and leads to tissue degeneration.

The radioactive materials are passed through the land to water and cause an adverse effect on the aquatic animals. They reach to human through the food chain. The nuclear power generates a lot of energy which is used to run turbines and produces electricity. The fuel and the coolant produce a large amount of pollution in the environment. The atomic reactors are also rich in the radioactive materials. There biggest problem is in their disposal and if they are not properly disposed they can harm the living organisms. If they escape they can cause a hell lot of destruction. The gases escape as a vapor and cause pollution on the land and water. The use of radioactive isotopes is multipurpose. They are of a great scientific value and they may be present in the waste water. From these water resources they reach to the human body via food chain. The people who work in power plants have more chances of the exposure to harmful radiations. The human beings also receive the radiation and radiotherapy from the x rays.
what is the effects of radioactive pollution?
ionizing radiation
ionizing radiation causes mutations, the random changes in the structure of DNA, the long polymer that contains the coded genetic information necessary for development and functioning of a human being. When a cell in which a mutation has occurred is in the germline (the egg and sperm cells), the mutation may be passed on the future generations.
increased radiation exposure by individuals is oftentimes seen as a cause of cancer. Exposure to radiation comes from several sources:
a. isotope therapy
b. x-ray diagnosis and therapy
c. fallout from testing of nuclear weapons
d. radiation pollution from nuclear reactors
e. radioactive substances and wastes
most of the dangerous radioactive isotopes are continually released in small quantities into the air and water by nuclear plants. Within the next century, krypton-85 could raise the level of radiation exposure of general population to 60% of the maximum permissible level set by the national committee on radiation protection and measurement.
effects of uv-b radiation
on land, uv-b radiation endangers all living forms. For instance, a person exposed to a high level of uv-b will find his/her immune system deteriorating. He/She becomes more prone to diseases and other disabilities such as skin cancer, eye cataract and blindness. Moreover, he/she ages more rapidly. More importantly,human sources of food become more limited since UV-B stunts the growth of crops and trees
ways to prevent or stop radioactive pollution & radiation
Radiation Pollution Control can be done at various levels, including the handling and treatment of radiation waste, the control and mitigation of nuclear accidents, as well as the control and minimization of personal exposure to radiation at an individual level.

Treatment of radiation waste cannot be done through degradation by chemical or biological processes. Additionally, many radioactive materials have very long half-times (time necessary for half of the material to degrade or transform into non-radioactive materials) and thus radiation waste may pose a risk for many years after it was produced. Basically, there are only few options for radiation waste treatment involving:


Containment of the waste in radiation-shielded containers usually buried under ground
Isolation of radiation waste in remote locations such as remote caves or abandoned mines - which may also involve the use of some kind of barriers (shields),
When the first two alternatives are not possible, the waste may be diluted till background values are achieved.
Heat and Radiation Pollution – basically radiation is a method of heat transfer. While radiation may be generated in any conditions, the heat increases the amount of radiation and thus may increase the health risk. For example, radiation is concentrated in the ash due to burning processes. Also, the higher the heat, the higher the energy of radiation produced (e.g., UV rays are produced by hot bodies such as the sun). This is why radiation waste should be stored in cold places, away from any heating source.
Law Enforcement for Radiation Pollution Control – in the U.S., environmental standards designed tom protect human health from radiation are issued by EPA along with guidance for federal agencies related to radiation exposure standards/limits. The Nuclear Regulatory Commission (NRC) is the federal agency responsible to implement some of the EPA’s regulation and standards. The Department of Energy (DOE) implements the standards at their facilities.

At individual levels, there are measures you may take to prevent and/or reduce radiation pollution that may affect you and your family. Here are some examples:

First, testing of your home for radon may be done by each person using inexpensive testing kits or by specialized consulting services. If radiation seems to be an issue (a higher than background value of radon in home is found), a preferred radon reduction technique is the installation of a special system called active soil depressurization (ASD). This system contains a vent pipe with an inline centrifugal fan that operates continuously to vent radon and other intruding gases from beneath the house. Thus, the system may be efficient to block the intrusion into homes not only of radon, but also of other toxic chemicals (non-radioactive) that may get from the subsurface into indoor breathing air.
Choosing an appropriate location for your home – away from the main radiation pollution sources;

a.. isotope therapy
b. riding a bike
6-7.) give 2 effects of radiation
8.-10) give 2 ways to stop or prevent radioactive pollution
