Consensus regarding low-level radiation assessments and countermeasures: physical dosimetry.

One of the goals of the 1999 International Conference on Low-Level Radiation Injury and Medical Countermeasures was to review current and anticipated capabilities for measuring the quantity and quality of radiation exposures using personal dosimetry systems, fieldable spectroscopy equipment, and modeling strategies. Technological advances in these systems need to be evaluated for use in radiation exposure assessment. The conference focused on the application of these systems to military operations, emphasizing their use for radiation exposure assessment internationally.

Environmental monitoring technology.

As a consequence of the new geopolitical environment, missions of military forces have changed. Soldiers are now primarily involved in peacekeeping or humanitarian missions. Even the radiological threat has changed.

Effects of low-dose neutrons applied at reduced dose rate on human melanoma cells.

Human melanoma cells that are resistant to gamma rays were irradiated with 14 MeV neutrons given at low doses ranging from 5 cGy to 1.12 Gy at a very low dose rate of 0.8 mGy min(-1) or a moderate dose rate of 40 mGy min(-1).
