THE NATURAL RADIATION ENVIRONMENT

Background radiation, people and the environment

All living organisms are exposed to ionizing radiation comprising cosmic rays coming from outer space, terrestrial nuclides occurring in the earth’s crust, building materials, air, water and foods and in the human body itself. The exposures are constant and uniform for all individuals everywhere including the dose from ingestion of 40K in food. Cosmic rays are, more intense at higher alt...

Direct effects of radiation on the natural environment

by Abel J. González On 26 April 1986, a catastrophic explosion at Unit 4 of the Chernobyl nuclear power plant in the Ukrainian Republic — close to the point marking the three-way border with the Republics of Belarus and Russia — sent a very large amount of radioactive material into the atmosphere. The event was to become one of the most protracted and controversial themes of the modern technolo...

The Space Radiation Environment

The effects of the space radiation environment on spacecraft systems and instruments are significant design considerations for space missions. Astronaut exposure is a serious concern for manned missions. In order to meet these challenges and have reliable, cost-effective designs, the radiation environment must be understood and accurately modeled. The nature of the environment varies greatly be...
