QO
The National Institute for Occupational Safety and Health is presently
investigating health issues at the Gaseous Diffusion Plants that involve
information that is classified, restricted data. The NIOSH policy requires
them to conduct their studies unclassified, and with unclassified information.
It is possible, but much less desirable, to use information that is encoded in
such a way as to protect the specific classified information, and to have a
classified key to the encoding as a classified appendix to their report.

This request is intended to state the specific information that is required,
and the way the information wil? be used. The investigation covers any
occupational exposure to a list of specific chemicals, and will require any
data that are relevant to the exposures.
1) The chemicals of concern consist of two groups. The first group are taken
from the open literature about the gaseous diffusion plants. These are:
NICKEL
MERCURY
ACETONE
The classified com
COPPER
ARSENIC
URANIUM
FLUORINE
PERCHLORETHYLENE
CADMIUM
CARBON TETRACHLORIDE
PCB’S

A less desirable but possible alternative to naming the chemicals would be to
encode the names by using terms like “Particulate A, Particulate B, and
Chemical A, Chemical B." This approach would require the use of a classified
appendix with the decoding information in it.
2) The monitoring results that are used for dose calculation would include
volumetric concentrations of specific materials.
A less desirable form of the data would be an encoding of dosages into "High,
Medium, or Low" ranges, with the decoding of the ranges given in a classified:
appendix.
3) The monitoring data should be identified by the building and department
numbers to be correlated with worker exposure. It would be very useful to
include job titles.
A less desirable approach would be to identify buildings as "Building A,
Building B."
