Radioactive(放射性的) pollution can be said to be the emission(排放) of radioactive substance into air, water or land due to human activities in the form of radioactive waste. Radioactive waste is usually the product of nuclear fission(核裂变), which is widely used in nuclear power stations and nuclear weapons.

The radioactivity of nuclear waste decreases with time. That means the waste needs to be separated from the reach of living beings until it no longer causes a threat to living beings. This time period may take from days to months and to years depending upon the radioactive nature of the waste.

Radioactive pollution that is spread through the earth’s atmosphere is called ‘fallout’. Nuclear pollution began to attract people’s attention during the World War II period when the United States, Britain and the Soviet Union started conducing nuclear tests. The best example of fallout is the nuclear bomb attack on Hiroshima and Nagasaki, Japan in 1945 by the United States of America during World War II. As a result of the bomb attack, nearly 225,000 people died within 5 years of the attack due to the radiation effects and cancer.

In land and water, the major source of radioactive pollution remains with the nuclear fuel cycle(核燃料循环). The nuclear fuel cycle is used in nuclear power stations and extraction(提炼) of materials from nuclear substance, where the pollutants are left behind after the useful material has been extracted.

The effects of radioactive pollution were first reported in the early 20^th century when people working in uranium mines(铀矿井) suffered from skin burn and cancer. The effects vary from one individual to another. Exposed to radioactive radiations for a long time, living beings may suffer from the damage to the DNA cells, which results in cancer, genetic defects for the generations to come and even death.

In a word, since every coin has its two sides, it’s a good idea to prevent from its disadvantages while making full use of its advantages.

“Image is everything.” An entire industry has been built upon the assumption that image is everything, but when it comes down to it, an appealing image is not enough. If there is no substance（事实）behind the image, the product, service or person will fail eventually.

First of all, one should consider how important image is in the selling of products and services. Advertising agencies have raised the art of creating an image to a state of near perfection. Public concept of that product or service is certainly managed by the images created by the advertising agencies．But if the product or service does not live up to the image that was created, the customer will be very dissatisfied and possibly ask for their money back. For example, the Arthur Andersen accounting firm had spent decades building up an image of trustworthiness. But the recent scandal (丑闻) showed that behind that image, it cheated in business practices. Despite the previous positive image, the firm is being accused of criminal actions and it will probably not survive as a business unit. Although the image had been nearly perfect, the reality behind the image has led to the downfall of the world famous accounting firm.

Similarly, personal advisers can build up a public image for politicians and movie stars. Putting out positive news releases, making sure that only the best photographs are published, and ensuring that the person is seen in all the right places can build up a very positive image in the view of the general commons. But once again, history is filled with examples of both politicians and movie stars that fell from grace like the story of the Hollywood actor giving in to the pressures of fame and fortune. With people, just as with products and services, image is certainly important, but without positive substance behind the image, failure is close.

To summarize, it is clear that an appealing image is extremely important to success, whether that image is related to selling a product or service or to the “selling” of a person. But image is only half of the equation. What lies behind that image is every bit as important as the image itself —— the person or product must deliver on that image or there is little chance for long-term success.

“Image is everything.” An entire industry has been built upon the precondition that image is everything, but when it comes down to it, an appealing image is not enough. If there is no substance(物质) behind the image, the product, service or person will fail at length.

First of all, one should consider how important image is in the selling of products and services. Advertising agencies have raised the art of creating an image to a state of near perfection. Public concept of that product or service is certainly managed by the images created by the advertising agencies.

Similarly, personal consultants can build up a public image for politicians and movie stars. Putting out positive news releases, making sure that only the best photographs are published, and ensuring that the person is seen in all the right places can build up a very positive image in the view of the general commons. But once again, history is filled with examples of both politicians and movie stars that fell from grace(体面) like the story of the Hollywood actor giving in to the pressures of fame and fortune. With people, just as with products and services, image is certainly important, but without positive substance behind the image, failure is close.
