Nuclear Accidents
Nuclear Tests
In addition to the radionuclide differences
observed in hot particles from reactor accidents
and nuclear tests, there are physical and
radionuclide distribution differences in the hot
particles.
Particulate sampling is designed to capture and
measure these particles. However, as the
activity is mostly located in these particles, it is
highly likely that a non-homogeneous collection
would be observed.
This has implications for sample splitting and
duplicate sample analysis. Because of hot
particles, duplicate samples and splits of
samples will not be identical.

Introduction
Hot particles in the environment
are a common occurrence.
The presence of radionuclides
in these particles causes
special care in interpretation of
IMS particulate samples and
OSI samples.
There is ample data in the
literature that describes hot
particles in the environment.
Several examples from nuclear
accidents and nuclear tests are
described, with similarities and
contrasts highlighted.
