Could increase it to up to 2 Ci per week, but we should keep in mind that it could only be produced periodically as they use the same machine for other work as well. I could not obtain anything like a product fact-sheet, I assume it is similar to the Idaho one below. Argonne does not sell it like BNL. My understanding is that one would need to be in some collaboration with them in order to obtain Cu-67 and in each case the product may have different SA, purity, etc.</div><div><br>Idaho Accelerator Center:<br>Specific Actvity (mass): >10,000 mCi/mg, typically > 20,000 mCi/mg Actvity: 2-100 mCi (delivered)<br>Available: Weekly<br>Shipment: Shipped dry chloride form<br>Packaging: 2ml plastic v-bottom vial, crimp top</div><div>Not intended for human use<br></div><br><div>BNL:</div><div><table border="2" cellpadding="5" width="100%" style="color: rgb(0, 0, 0); font-family: Verdana, sans-serif; font-size: 14px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px;" data-mce-style="color: rgb(0, 0, 0); font-family: Verdana, sans-serif; font-size: 14px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px;"><tbody><tr><td align="center"><b>Form</b></td><td>Copper (II) in 0.1-1.0 <span style="text-decoration: underline;" data-mce-style="text-decoration: underline;">M</span> HCl</td></tr><tr><td align="center"><b>Activity</b></td><td>2-12 mCi/ug (specific activity)<br>>10-20 mCi/mL (concentration), or as<br>specified by user</td></tr><tr><td align="center"><b>Radiopurity</b></td><td>>99% (exclusive of Cu-64); the Cu-64 content is ~60% upon delivery (48 hours<br>past EOB)</td></tr><tr><th colspan="2"><i>PRODUCTION</i></th></tr><tr><td align="center"><b>Source</b></td><td>Spallation by protons on zinc-68 metal target</td></tr><tr><td align="center"><b>Processing</b></td><td>Dissolution, electrochemical deposition, and ion-exchange</td></tr><tr><th colspan="2"><i>DISTRIBUTION</i></th></tr><tr><td align="center"><b>Shipment</b></td><td>Crimp-seal bottle</td></tr><tr><td align="center"><b>Availability</b></td><td>Regular production</td></tr><tr><td align="center"><b>Unit of Sale</b></td><td>Millicuries</td></tr></tbody></table><br></div><div><br>--<br>George Kharashvili<br>Jefferson Lab Radiation Control<br>757-269-6435<br><br>----- Original Message -----<br>From: "George Neil" <neil@jlab.org><br>To: isotope-prod@jlab.org<br>Sent: Wednesday, July 26, 2017 5:06:17 PM<br>Subject: Re: [Isotope-prod] My talk in Quebec<br><br>Do we know anything about the (gamma, n) production approach that Argonne is using in terms of production rates, isotopic contamination, purity, etc?
