March 15, 2002: Nuclear Pollution and Cancer

By Mario Ritter

This is the VOA Special English ENVIRONMENT REPORT.

A recent report by the USA Today newspaper says that a large amount of nuclear pollution has caused thousands
of deaths in the United States. The radioactive¹ material was spread by tests of nuclear weapons carried out during
the Nineteen-Fifties and early Nineteen-Sixties.

The news report is based on a study done by the United States Centers for Disease² Control and
Prevention and the National Cancer Institute. However, the Department of Health and Human
Services has not released³ the study to the public. The study says that a larger area than
expected received high levels of nuclear pollution.

The study used computer models to find out where nuclear pollution may have fallen. The

study says all people living in the United States since Nineteen-Fifty-One have received some
level of radiation. It says people in the most affected⁴ areas received radiation equal to one medical x-ray every
year.

Beginning in the Nineteen-Fifties, the American military carried out more than two-hundred tests of nuclear
weapons. About half of those tests were done in the state of Nevada. During the same period, the former Soviet⁵
Union carried out a similar number of tests on its own territory. Britain and the United States carried out other
nuclear tests on islands in the Pacific Ocean. The study says that these tests also spread radioactive material in
America. The United States halted⁶ above-ground nuclear tests in Nineteen-Sixty-Three.

The study also estimates⁷ that at least eleven-thousand Americans may have died of cancer as a result of nuclear
pollution. It says thousands of other people developed non-deadly forms of cancer.

Yet, some medical experts say that it is very difficult to point to a single cause for many kinds of cancer. They
also say the number of deaths caused by radiation is small when compared to the number of people who have
died from other causes, such as smoking.

However, experts say nuclear pollution is an environmental problem that can last a long time because of the
nature of radiation. Some radioactive material remains⁸ dangerous for only a few years. But other material is
dangerous for much longer periods.
