>From Robinson NP - We use it at 3% strength. We have seen good decon results. You need to let it soak a minute before washing off. Lower cavity had up to 80,000 dpm alpha and after decon was less than MDA.

Exercise caution. DO NOT open attachments or click links from unknown senders or unexpected email. *** Question from LaSalle: We are reviewing use of hydrogen peroxide in the reactor cavity. We are working through the chemistry concerns before implementing it. Items of interest include strength of solution, lessons learned, method of application, estimated dose savings, station contacts (RP and Chemistry) , etc. Any associated post-job reviews would be most helpful. No response is required if you do not use it for cavity decon. Thanks in advance for your assistance!
