Please amend the above subject license to include the addition of 3 P odiu.
Beryllium neutron sources which are at present under our New York State Health Department license number 1035.
These sources are being used in student labor-atory activities such as activation analysis and instrument calibration.
Per-tinent data associated with these sources are as follows:
Identification Number Weight % Isotope Isotope (Pu 239) Weight (grams)-
N320C29 93.03 29.77 N320C30 93.C3 29.77 N320C31 93.03 29.77 Total 89.31 grams All the above sources are approximately 1.86 curies of Plutonium 239 and are doubly encapsulated in stainless steel. All have been leaked checked by the swipe technique and no detectAle radioactivity was found. The sources are in a locked container, within a locked area of Rensselaers Sub-critical Facility in a building designated Blow-Knox I.
I hope the above meets witn pur needs.
Sincerely,
