The Radiation Safety Office Newsletter

Volume II   Number 2        For the University of Maryland Campus       October 13, 1998

The Radiation Safety Office at the University of Maryland shall publish a Newsletter on topics concerning Radiation Protection and Use of Radioisotopes and Radiation Producing Devices. The last issue was about the Maryland Department of Environment inspections of the University license through its Radiological Health Section. This issue discusses Radioactive Orders offered by our Radiation Safety Office.

The possession and use of radioactive materials is restricted to personnel who are currently authorized by the Radiation Safety Officer and/or the Radiation Safety Committee and is limited to those isotopes in the physical form and activity specified in the authorization. All orders for radioactive material must go through the Radiation Safety Office.

For orders under $1000:

1. The Department of Environmental Safety has blanket purchase orders with popular suppliers (Amersham, ICN, NEN). Orders for these vendors must be submitted on a University of Maryland, College Park Internal Request of Services form.
2. We do not have a blanket purchase order with all vendors. Complete a Small Procurement Order form for radioactive orders with other vendors (Linco Research, Diagnostic Products Corp., American Radiolabeled Chem., Sigma, etc). Forward it to the Radiation Safety Office. On this form, it is particularly important to have the correct address and telephone number for the vendor.

Only the Radiation Safety Office can call in this category of orders.

The paperwork to send the orders to the vendor must contain the following information. First, every order must have the principal investigator's name. This provides the name of the person authorized to possess radioactive material; in addition, we use it for inventory control.

Second, the catalog number for the order must be exact. Many times, typographical errors cause mis-orders and result in unnecessary costs. Following the catalog number, write a description of the radionuclides. This would include:

Radioisotope: P-32, S-35, H-3, C-14, P-33, I-125, etc

Label: Gamma, alpha

Chemical compound: dATP, ATP, CTP, etc

Activity: in millicurie or microcurie amounts 250 µ Ci or .25 mCi,

Vendor name: Amersham, NEN, ICN

Orders over $1000:

For orders over $1000 and other supplies, submit information on the regular Requisition of Supplies and Equipment Form. The requisition will be processed through the Radiation Safety Office and will be forwarded to Campus Purchasing with a letter indicating the requestor is authorized to order and receive radioactive materials. Purchasing will not process a requisition for radioactive material without the authorization letter.
