چکیده

When people think of atomic energy they often have nuclear reactors in mind. Few, however, realize that another aspect of atomic energy has changed their daily lives during the last 20 or 30 years. When the International Atomic Energy Agency came into being in 1957, one of its major initial objectives was to promote the wider use of radioisotopes and radiation sources in research, industry, agriculture and medicine. Today few people are aware of the extent to which this objective has been achieved. For example, radioisotopes and controlled radiation are used to improve food crops, preserve food, determine groundwater resources, sterilize medical supplies, analyse hormones, X-ray pipelines, control industrial processes and study environmental pollution. A great many of the objects we use in our daily life have in some way benefited from radiation during their production.

The US national isotope program: current status and strategy for future success.

Since their introduction in the 1940s, peaceful use of stable isotopes and radioisotopes in the United States has expanded continuously. Today, new isotopes for diagnostic and therapeutic uses are not being developed, critical isotopes for national security are in short supply, and demand for isotopes critical to homeland security exceeds supply. While commercial suppliers, both domestic and fo...

Decay data of radionuclides along the valley of nuclear stability for astrophysical applications.

Several directions of the demand for decay data in nuclear astrophysics are discussed for radionuclides near the valley of nuclear stability. The current half-life and gamma-ray intensity evaluation results are presented for some radionuclides of astrophysical interest. An extended list of such nuclides is offered for their nuclear characteristics to be further evaluated by the Decay Data Evalu...
