[ RadSafe ] Use of signs to caution workers of high alpha contamination areas

[WHILLANS David -NUCLEAR]

The new EPRI Alpha Monitoring Guidelines for Operating Nuclear Power Stations suggest the use of postings to caution workers of potentially-high alpha contamination areas.

Have any utilities implemented this recommendation? Do you post for alpha Levels I, II and III (and include the beta-gamma/alpha ratio?) or simply post current high alpha contamination results?  Are there any specific wordings that have been found particularly effective?

Please send responses to
