This work quantifies the adsorptive uptake of radium‐226 from solution by the walls of the solution container. Three different container materials were examined, each with significantly different critical surface tension. Teflon was shown to be the material with the least radium‐226 adsorption capacity in the examined pH range of 2 to 10. The radium adsorption by Teflon flasks is consistent and predictable. The respective adsorption isotherm is presented. An optimum washing procedure for the Teflon flasks was also defined.
