“…Early studies of 210 Pb in the environment included methodologies where 210 Pb was determined by the ingrowth of 210 Po (e.g., Burton and Stewart 1960;Hill 1960;Holtzman 1966;Shannon et al 1970) as well as 210 Bi (e.g., Blifford et al 1952;Burton and Stewart 1960;Rama and Goldberg 1961;Fry and Menon 1962;Craig et al 1973). Comparisons of the two approaches showed similar levels of precision.…”

210 Bi (t 1/2 : 5.01 d)-the daughter of 210 Pb and parent of 210 Po-has rarely been measured in aquatic systems, and its behavior in the water column is poorly understood. In this article, I present a method for quickly measuring 210 Pb, 210 Bi, and 210 Po in aquatic samples, where (1) 210 Bi and 210 Po are scavenged onto an anion solidphase extraction disk within 15 min of pretreating the sample; (2) beta decay of 210 Bi is counted on the disk immediately thereafter; (3) 210 Po is subsequently removed from the disk and redeposited on a copper plate for α-spectroscopy; and (4) 210 Pb is determined via the ingrowth of 210 Bi. I present decay-corrected calculations for total, dissolved, and particle-bound fractions of each nuclide and conclude with an analysis of 210 Pb, 210 Bi, and 210 Po activities in rain, dreissenid (quagga) mussels, and water samples from the Milwaukee Inner Harbor in Lake 157 WaplesMeasuring 210 Bi, 210 Pb, and 210 Po

“…Currently, 210 Po has been found to be widely distributed in a variety of environmental and biological samples [1,18,19], such as groundwater [20][21][22], fish, and shellfish [20,23,24]. 210 Po in environmental media can enter the body through inhalation, diet, drinking water, open wounds, and the food chain [17,25].…”

“…Currently, the treatment of water samples is often carried out using evaporation, co-precipitation, and chelation methods [26]. Due to its simple operation process when processing large-volume water samples, the direct evaporation method is preferred for concentrated environmental water samples [20,51]. However, evaporation is extremely time-consuming when processing large volumes of samples (>1 L), so the method is not suitable for radiological emergencies involving 210 Po or samples containing large amounts of dissolved impurities [52].…”

Ingestion of polonium-210 from environmental media and food can cause serious health hazards (e.g., gastrointestinal symptoms, tumours, etc.) and has been a public health concern worldwide since the 2006 poisoning of Agent Litvinenko 210Po in Russia. With the development of uranium mining and applications of nuclear technology in recent decades, the radioactive hazards posed by 210Po to living organisms and the environment have become increasingly prominent. In order to strengthen the monitoring of environmental 210Po and protect both the environment and human health, a series of explorations on the methods of 210Po determination have been ongoing by researchers across the globe. However, previous reviews have focused on individual sample types and have not provided a comprehensive account of environmental, food, and biological samples that are closely related to human health. In this work, the sources, health hazards, chemical purification, and detection methods of trace 210Po in different sample types are systematically reviewed. In particular, the advantages and disadvantages of various pretreatment methods are compared, and relevant domestic and international standards are integrated, which puts forward a new direction for the subsequent establishment of rapid, simple, and efficient measurement methods.
