“…Radioactive elements can adhere to sediment phases from the aqueous phase by physical processes (e.g., sedimentation), chemical (e.g., polymerization, colloidal clustering/aggregation, ion exchange), and biological (e.g., detritus) processes (van Hullebusch et al, 2005;Vives i Batlle, 2012). Remobilization of NORMs and radioactive contamination from sediments to water may occur via natural or anthropogenic perturbation and resuspension, e.g., mineral or crude oil exploration, transportation, flooding, dredging or constructions, hurricane, etc.…”

Several anthropogenic activities produce radioactive materials into the environment. According to reports, exposure to high concentrations of radioactive elements such as potassium ( 40 K), uranium ( 238 U and 235 U), and thorium ( 232 Th) poses serious health concerns. The scarcity of reviews addressing the occurrence/sources, distribution, and remedial solutions of radioactive contamination in the ecosystems has fueled data collection for this bibliometric survey. In rivers and potable water, reports show that several parts of Europe and Asia have recorded radionuclide concentrations much higher than the permissible level of 1 Bq/L. According to various investigations, activity concentrations of gamma-emitting radioactive elements discovered in soils are higher than the global average crustal values, especially around mining activities. Adsorption technique is the most prevalent remedial method for decontaminating radiochemically polluted sites. However, there is a need to investigate integrated approaches/combination techniques. Although complete radionuclide decontamination utilizing the various technologies is feasible, future research should focus on cost-effectiveness, waste minimization, sustainability, and rapid radionuclide decontamination. Radioactive materials can be harnessed as fuel for nuclear power generation to meet worldwide energy demand. However, proper infrastructure must be put in place to prevent catastrophic disasters.

“…Marine organisms possess natural chemical compounds which show protection against harmful radiations and multiple radioactive contaminations from industries and nuclear plant (Batlle 2012 ). A number of in vitro and in vivo studies were carried on marine-derived compounds to understand their radioprotective activity and mechanism against different ionizing radiations (Chrapusta et al 2017 ).…”

Natural extracts and compounds from marine resources have gained intensive scientific and industry attention for radioprotective activities in the past ten years. However, the marine-derived radioprotectants have been studied against UV-rays, gamma (γ)-rays and X-rays for more than 30 years. This review aims to identify key marine-derived extracts/compounds and their modes of action studied for radioprotective activities from 1986 to 2019. A comprehensive survey was conducted to establish the trend in terms of the publications each year and the countries of origin. A total of 40 extracts and 34 natural compounds showing radioprotective activities against UV-rays, gamma (γ)-rays and X-rays were identified from a range of marine plants and animals. These extracts and compounds are broadly categorized into polysaccharides, phlorotannins, carotenoids and mycosporine-like amino acids (MAAs). Macroalgae and microalgae were found to be the dominant sources of polysaccharides, phlorotannins and carotenoids. MAAs were mainly identified in algae, sponges, sea cucumber and corals that showed significant UV-absorbing activities. A number of radioprotective mechanisms were shown by these compounds, predominantly free radicals scavenging, inhibition of apoptosis, UV-ray absorption and DNA damage-repair signaling pathways. While these bio-discoveries warrant further investigation and development of radioprotective therapeutics, however, the lack of clinical studies is a major obstacle to be tackled in the future.

“…CR wo and l is the radionuclide decay constant (Vives i Batlle, 2012). This type of model can be simplified by assuming that the water concentration does not depend on the exchange from an aquatic organism (because the amount of radioactivity in the organism is much smaller than in the surrounding volume of water, V) e hence dA W /dt z 0, and that the organism uptake rate does not change with time (i.e.…”
