This is ridiculous. You have no research just assumptions type in 'Chernobyl children' in any search engine my friend and don't forget the images.
By 2000 about 4000 cases of thyroid cancer had been diagnosed in exposed children. Among these, nine deaths are attributed to radiation. However, the rapid increase in thyroid cancers detected suggests that some of it at least is an artifact of the screening process.
People in the area have suffered a paralyzing fatalism due to myths and misperceptions about the threat of radiation, which has contributed to a culture of chronic dependency. Some "took on the role of invalids”
The New York Times wrote article after article about how radiation would change Japanese lives "for "centuries," that there would be genetic damage -- defects for the next 1,000 years. But surprise: So far no such damage has appeared. Some researchers, like toxicology professor Ed Calabrese, now say blast survivors, who were exposed to smaller amounts of radiation, are living longer than normal, and in small doses, radiation may even be good for you. "It's all in the dose," Calabrese said. "What's going on at low doses is often seen to enhance immune performance and enhance longevity," he said.
While plutonium is sometimes described in media reports as "the most toxic substance known to man", from the standpoint of actual chemical or radiological toxicity this is incorrect…From a purely chemical standpoint, it is about as poisonous as lead and other heavy metals. Not surprisingly, it has a metallic taste.
As it stands, nuclear power is the only environmentally friendly, economic, and efficient source of energy that can help the U.S. wean itself off foreign oil. Solar and wind will never meet our demand, and bio-fuels are still years--if not decades--away from becoming viable.
Gwyneth Cravens's illuminating “Power to Save the World: The Truth about Nuclear Energy” dispels many of the myths about nuclear energy. For example, she notes coal plants emit more radiation than nuclear ones. Also, nuclear energy plants are almost completely risk-free regarding nuclear weapons proliferation (it's a different enrichment process) and potential terrorist attacks (U.S. plants are simply too secure)
One of the most important lessons: that customized designs can create inefficiencies, duplication of effort and higher costs-brought about a fundamental change in industry practice: design standardization.
Most of America's operating nuclear power plants are virtually one-of-a-kind, because they were designed and built at a time when regulatory requirements, licensing standards and the technology were evolving rapidly.
The French nuclear program is based on standardized nuclear plant designs. Over nearly two decades, the French built 34 standardized 900-megawatt units and 20 1,300-megawatt units, which now supply about 75 percent of that country's electricity.
By using standardized designs, the French were able to cut construction times significantly. The first reactors in the 900-megawatt series took about seven years to build; the last reactors, only five years. Because of standardization, the cost of nuclear power plants in France is among the lowest in the world.
Within a short time after the nuclear disaster, a sharp increase in reproductive disorders - predominantly affecting pregnancy - was noted in Ukraine and Belarus. For the 1986-1990 period, the Ministry of Health in Ukraine recorded an increased number of miscarriages, premature births and stillbirths, as well as three times the normal rate of deformities and developmental abnormalities in newborns
New research findings presented at the "Health Consequences of Chernobyl Children" symposium in Basel in 2003 show that infant mortality and the incidence of stillbirths and birth defects rose significantly in parts of Germany and other European regions exposed to high levels of radiation following the reactor disaster
When uranium (U-235) nuclei are split in a nuclear reactor, various radioactive fission products arise. In terms of harmful impact, the most relevant of these are iodine-131, caesium-137, strontium-90 and plutonium-239. These elements are spread via aerosols (dust particles in the air) and may be inhaled, deposited in the earth by rainfall and water, or enter the food chain via plants.
It is heartbreaking to think of all the people who spent 20 years after this disaster, falsely expecting to get cancer and die an early death, just so western news outlets like the Daily Telegraph and the BBC could sell more advertisements and make a little more money.

Only part 1 of 3. All 3 are available at the link as well.
BTW, my speakers have stopped working on my PC, so if this isn't the right episode, let me know.
The fact that coal-fired power plants throughout the world are the major sources of radioactive materials released to the environment has several implications. It suggests that coal combustion is more hazardous to health than nuclear power and that it adds to the background radiation burden even more than does nuclear power. It also suggests that if radiation emissions from coal plants were regulated, their capital and operating costs would increase, making coal-fired power less economically competitive.
Finally, radioactive elements released in coal ash and exhaust produced by coal combustion contain fissionable fuels and much larger quantities of fertile materials that can be bred into fuels by absorption of neutrons, including those generated in the air by bombardment of oxygen, nitrogen, and other nuclei with cosmic rays; such fissionable and fertile materials can be recovered from coal ash using known technologies. These nuclear materials have growing value to private concerns and governments that may want to market them for fueling nuclear power plants. However, they are also available to those interested in accumulating material for nuclear weapons. A solution to this potential problem may be to encourage electric utilities to process coal ash and use new trapping technologies on coal combustion exhaust to isolate and collect valuable metals, such as iron and aluminum, and available nuclear fuels.
Since the 1960s particulate precipitators have been used by U.S. coal-fired power plants to retain significant amounts of fly ash rather than letting it escape to the atmosphere. When functioning properly, these precipitators are approximately 99.5% efficient. Utilities also collect furnace ash, cinders, and slag, which are kept in cinder piles or deposited in ash ponds on coal-plant sites along with the captured fly ash.
Trace quantities of uranium in coal range from less than 1 part per million (ppm) in some samples to around 10 ppm in others. Generally, the amount of thorium contained in coal is about 2.5 times greater than the amount of uranium. For a large number of coal samples, according to Environmental Protection Agency figures released in 1984, average values of uranium and thorium content have been determined to be 1.3 ppm and 3.2 ppm, respectively. Using these values along with reported consumption and projected consumption of coal by utilities provides a means of calculating the amounts of potentially recoverable breedable and fissionable elements (see sidebar). The concentration of fissionable uranium-235 (the current fuel for nuclear power plants) has been established to be 0.71% of uranium content.
Using these data, the releases of radioactive materials per typical plant can be calculated for any year. For the year 1982, assuming coal contains uranium and thorium concentrations of 1.3 ppm and 3.2 ppm, respectively, each typical plant released 5.2 tons of uranium (containing 74 pounds of uranium-235) and 12.8 tons of thorium that year. Total U.S. releases in 1982 (from 154 typical plants) amounted to 801 tons of uranium (containing 11,371 pounds of uranium-235) and 1971 tons of thorium. These figures account for only 74% of releases from combustion of coal from all sources. Releases in 1982 from worldwide combustion of 2800 million tons of coal totaled 3640 tons of uranium (containing 51,700 pounds of uranium-235) and 8960 tons of thorium.
Based on the predicted combustion of 2516 million tons of coal in the United States and 12,580 million tons worldwide during the year 2040, cumulative releases for the 100 years of coal combustion following 1937 are predicted to be:
U.S. release (from combustion of 111,716 million tons):
Uranium: 145,230 tons (containing 1031 tons of uranium-235)
Thorium: 357,491 tons
Worldwide release (from combustion of 637,409 million tons):
Uranium: 828,632 tons (containing 5883 tons of uranium-235)
Thorium: 2,039,709 tons
Thus, by combining U.S. coal combustion from 1937 (440 million tons) through 1987 (661 million tons) with an estimated total in the year 2040 (2516 million tons), the total expected U.S. radioactivity release to the environment by 2040 can be determined. That total comes from the expected combustion of 111,716 million tons of coal with the release of 477,027,320 millicuries in the United States. Global releases of radioactivity from the predicted combustion of 637,409 million tons of coal would be 2,721,736,430 millicuries.
