Posting of "Beta" Radiation Areas
Beta dose could be considered a risk issue for DDE for the eyes. In most
power plants, workers typically wear safety glasses or other types of eye
protection which provide sufficient shielding that DDE to the eyes is not of
concern. It seems to me that in order to protect a site from regulatory
interpretation and variability of interpretation, the best thing to do is to
develop and approve a Technical Basis Document which details the site
position on this subject, technical basis and any limitations or precautions
to be considered in procedural implementation. Having done that, it would
seem that no routine posting for radiation areas due to beta would be
necessary. Remember to be circumspect, because there is always a small
probability that work may occur in some special circumstance where dose from
beta to the eyes might need to be considered and in that situation, postings
should be considered depending on the other work controls and necessity to
warn other workers of the dose hazard.
Thanks!
