The concentration of cesium-137 source is measured using the radioactive decay of cesium shielded by aluminum. The painted aluminum chassis was obtained from a previous team at UW, and modified using plastic k’nex toys to adapt to the current power source and stopping mechanism.enghttps://creativecommons.org/licenses/by/4.0/chemical engineeringAIChEradiationrumenmicrobial electrolysis cellsChemE Carthesis
