Notice of Intent to Noncompetitively acquire a hexapod component of extrapolation chamber for measuring absorbed dose from alpha-emitting sources.
This notice is not a request for a quotation. A solicitation document will not be issued, and quotations will not be requested.
This acquisition is being conducted under the authority of FAR 13.106-1(b). The North American Industry Classification System (NAICS) code for this acquisition is 334516 - Analytical Laboratory Instrument Manufacturing, with a small business size standard of 1,000 employees.
The National Institute of Standards and Technology (NIST) has a requirement for a Hexapod component for an extrapolation chamber to establish a new capability to measure the absorbed dose from alpha-particle emitting sources. A collaborative project has been initiated between the Radioactivity and Dosimetry Groups at NIST and the University of Wisconsin to characterize radionuclides (such as Ac-225) for application in targeted alpha therapy to treat various types of cancer. The Radioactivity Group will develop methods used to fabricate alpha-particle-emitting radioactive sources and measure the absolute activity of these sources. The Dosimetry Group will measure the absorbed dose due to the sources, which will complement the activity measurements, fully characterizing the source and providing valuable information relevant to clinical treatment planning. In order to perform absorbed dose measurements, a specialized instrument called an extrapolation ionization chamber is required. Extrapolation chambers used to measure beta-emitting sources are commercially available, but they cannot be used to measure alpha-emitting sources as required by this project. The University of Wisconsin has built an extrapolation chamber specifically designed to measure the absorbed dose from alpha-emitting sources. The Dosimetry Group needs to purchase an identical Hexapod, a critical component, that will ... - Documents :
