Effects of Low Dose Radiation on Mammals 1

Radiation has been applied widely to clinics, researches and industries nowadays. Irradiation by atomic bomb produced many victims in Hiroshima and Nagasaki. Radiation effects on animals and human belings have been reported extensively, especially at a dose range of high amount of radiation. As radiation effects at low dose have not been well studied, it is believed that even a small amount of radiation produces hazardous effects. However, it might not be true. Beneficial effects of a low dose of radiation are summarized here

Effects of the Atomic Bomb Explosion in Nagasaki : A Medical Perspective 1

A review of the medical effects of the Nagasaki atomic bomb explosion encountered between 1945 and 1990 was conducted. In the early stage, severe and various manifestations due to a combination of heat rays, blast and radiation were detected, but the accurate number of deaths among victims during this early period remains obscure. Keloid scars, cataract, leukemia, thyroid cancer, breast cancer and lung cancer have been established as diseases related to the atomic bomb explosion. Recent epidemiologic investigations show that the incidence of other diseases such as gastric cancer and skin cancer are also relatively high among atomic bomb survivors in Nagasaki

Mortality of Atomic Bomb Survivors in Nagasaki 1

In 1945, an atomic bomb was exploded on Nagasaki. The Scientific Data Center for the Atomic Bomb Disaster was founded in Nagasaki University to analyse radiation effects on atomic bomb survivors. There were about 110,000 victims registered living in Nagasaki as of 1968. Since then, data of 2,000,000 items of health examination has been stored in the computer in the Scientific Data Center. The analysed results of the mortality, the survival and the risk estimation were presented
