Flood source with pigmentless active area and visible border

摘要

Method and/or system for forming a radiation flood source. The radiation flood source includes a paper sheet, a pigmentless radioactive fill printed on the paper sheet, and a pigmented border printed on the paper sheet and around the pigmentless radioactive fill. In one embodiment the radiation flood source is formed by preparing a radioactive isotope carrier solution; loading the radioactive isotope carrier solution into a radioactive isotope carrier solution cartridge; loading a separate border cartridge into a plotter; selecting and configuring a shape of an active area; setting a border to be placed around the active area; printing the active area by utilizing the radioactive isotope carrier solution cartridge on a sheet substrate; and printing the border by utilizing the separate border cartridge on the sheet substrate.
