Gemstone Irradiation and Radioactivity

TriGS - A Trigger System for GemStone

Active object-oriented concepts are especially useful in the area of nonstandard applications in order to express an event-driven and constraint-driven system environment [Chak90, Daya88b, Ahme92]. Several attempts have been made to integrate active concepts into object-oriented databases [Beer91, Daya88a, Diaz91, Gatz91, Geha91, Kim92, Mede91]. Current approaches to active objectoriented datab...

I.1.3. Study of Advanced Candu Fuel Radioactivity Evolution with Irradiation by Using Burnable Neutron

Radiation-modified natural zeolites for cleaning liquid nuclear waste (irradiation against radioactivity)

There have been comparatively few investigations reported of radiation effects in zeolites, although it is known that these materials may be modified substantially by exposure to ionizing radiation. Thus, by exposure to γ-rays or high-energy particles, the charge states of atoms may be changed so to create, and accumulate, lattice point defects, and to form structurally disordered regions. Such...

Radioactivity and thyroid cancer.

There is no evidence that natural radiation (cosmic radiation or from natural radioiosotopes) increases the risk for thyroid diseases. Moreover, while it has been proven that exposure to external medical radiation or to external and internal radiation by atomic bomb explosions leads to an increased risk for thyroid cancer, the medical use of radioiodine, namely diagnostic and therapeutic applic...
