Builders were tearing down an old chimney in a house in England when they found a letter. A little boy about 73 years ago addressed the letter to Father Christmas (Santa).

                       Hiroshima and Nagasaki Bombings

In August 1945, the US dropped two atomic bombs on the Japanese cities of Hiroshima and Nagasaki. The US said that they wanted to end World War II more quickly and to save American lives. However, officials estimate that 120,000 people died in Hiroshima and 74,000 people died in Nagasaki. Many people died within days after the bombings. They had health problems connected with the radiation. People who survived are now usually in their 80s and 90s. They still remember the bombings, and the events are a traumatic experience for them. However, many people have cancer, which is the main and the most dangerous effect of radiation. US and Japanese scientists study radiation together. Scientists check safe radiation limits for hospitals and for space missions.
