ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Radiation Protection & Shielding
The Radiation Protection and Shielding Division is developing and promoting radiation protection and shielding aspects of nuclear science and technology — including interaction of nuclear radiation with materials and biological systems, instruments and techniques for the measurement of nuclear radiation fields, and radiation shield design and evaluation.

Nominations open for CNTA awards
Citizens for Nuclear Technology Awareness is accepting nominations for its Fred C. Davison Distinguished Scientist Award and its Nuclear Service Award. Nominations for both awards must be submitted by August 1.
The awards will be presented this fall as part of the CNTA’s annual Edward Teller Lecture event.
Ionizing radiation affects living things on the atomic level by ionizing cells. When the radiation reaches a cell, any of the following can happen.
In addition, there is evidence to suggest that unless radiation exposure reaches ten (10) times the normal background level, there is no harm to humans from radiation. Furthermore, there appears to be evidence that radiation at or near the normal background level may be beneficial to, and even necessary, for life.
For low levels of radiation exposure (under 10,000 mrem), the biological effects are so small they may not be detected at all. The body’s natural repair mechanisms often repair any damage to the cells before any effect is felt or detected. This protective effect of low levels of radiation is called “radiation hormesis.”
