The development of nuclear science and technology has led to the increase of nuclear wastes containing radionuclides to be released and disposed in the environment. Pollution caused by radionuclides is a serious problem throughout the world. To solve the problem, substantial research efforts have been directed worldwide to adopt sustainable technologies for the treatment of radionuclide containing wastes. Biosorption represents a technological innovation as well as a cost effective excellent remediation technology for cleaning up radionuclides from aqueous environment. A variety of biomaterials viz. algae, fungi, bacteria, plant biomass, etc. have been reported for radionuclide remediation with encouraging results. This paper reviews the achievements and current status of radionuclide remediation through biosorption which will provide insights into this research frontier. This paper reviews the achievements and the current status of radionuclide remediation through biosorption. To attract more usage of biosorption technology, some strategies have to be developed where further processing of biosorbent can be done to regenerate the biomass and then convert the recovered radionuclide into a usable form. {\textcopyright} 2012 WILEY-VCH Verlag GmbH {\&} Co.
