Analyses of the environmental and biological effects of
radiation are based on and supported by qualified techniques and technologies.
This department maintains conventional techniques and carries out improvements
to the current technology for radiation protection research.
Advanced Analytical
Technology Section
This section has equipment for microanalysis technology
which combines chemical analysis with high-performance detectors such as ICP-MS.
Here the measurements
of trace elements important for their environmental effects are performed.
Animal Pathology Section
This section conducts detailed histopathological analyses
of radiation biological effects in experimental animals and provides collaborative
and consultative
experimental pathology support for NIRS intramural research. It provides
standardized routine and specialized histopathology techniques, and develops
new methods and technologies in experimental animal pathology.

Advanced Animal Research Section
This section supports integrated research of molecular and genetic studies
with physiological studies in whole animals. Although remarkable progress
of radiation biology has been made in genetic, molecular and cellular levels,
physiological analysis of whole animal models is inevitable for extrapolation
to human health.
The group supports production of "gene-modified mice"in which spcific
radiation-related gene(s) were introduced or deleted.
Analysis of such animals allows molecular and cellular
studies to correlate with physiological studies.
Environmental Radioactivity Survey Section
This section works for the advancement of atmospheric radioactivity measuring
techniques. Since this field is closely associated with health effects, such
as that of radon, the section contributes to the risk assessment of environmental
radioactivity.
