    discusses a combined radiochemical procedure that has been applied for the sequential determination of 90Sr, Am and Pu radioisotopes in environmental samples such as soil, sediment, air filter and vegetation samples. A great variety of methods have been developed for the determination of plutonium radioisotopes as well as Am and 90Sr. most environmental samples have low levels of Pu, a high degree of radiochemical purification is required in order to eliminate interferences from other environmental radionu-clides. This has been successfully achieved by separation and purification steps involving the use of ion chromatogra-phy or liquid–liquid extraction methods [5,12,13].

    The Environmental Radioactivity Analysis Laboratory (ERAL) was established as an analytical facility. The primary function of ERAL is to provide fast and accurate radiological data of environmental samples. Over the years, many radiochemical procedures have been developed by the staffs of .

A radiochemical method for the simultaneous determination of Pu + Pu and Pu in environmental samples has been developed.

In the course of the analysis a Pu tracer was used for estimating the chemical yield of plutonium isotopes. After suitable pre-treatment of the sample, the plutonium nuclides in solution were coprecipitated with iron(lll) hydroxide and calcium oxalate and.

A radiochemical method, previously applied to marine samples, was improved for the proper determination of Pu isotopes in environmental samples (soils, sediments and peats) by alpha-particle spectrometry. Samples were ashed at °C for 24 hours.

A radiochemical separation procedure has been developed for a very efficient isolation of plutonium from environmental samples. Essentially, the method involves the following steps: ashing of the sample and preparation of the load solution; separation of plutonium by a column containing a commercially available, highly specific, supported extractant; electrodeposition of Pu and subsequent Cited by: Rapid and Simultaneous Determination of Neptunium and Plutonium in Environmental Samples Using Anion Exchange Chromatographic and Sequential Injection Setup discussion of present radiochemical procedures for the individual radionuclides applied in the radiochemical separation and determination of radionuclides.
