All, I have been tasked with finding an Area Monitor to be placed at one of the Blood Bank Irradiators . It needs to have a visible and an audible alarm that can be set around 3 mR/hr. No other indications are necessary. Does anyone out there have a similar instrument or a recommendation for one? Please feel free to respond off-line. Sincerely, David M Kershman Office (314) 362-2996 Pager (314) 294-8392
