The potential utility of selective area chemical-deposition technique in the preparation of 147 Pm source for the measurement of particulate emission in air was demonstrated. The process consists of electrodeposition of Ni on a precisely defined surface area of a copper wire followed by deposition of 147 Pm activity from an aqueous solution. The influences of various experimental parameters such as pH of the aqueous solution, deposition time and reaction volume were systematically investigated for the optimum deposition of 147 Pm. To prevent leaching of 147 Pm from the source, we subsequently sheathed the radioactive area with a thin layer of polystyrene. The deposited films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and atomic force microscopy (AFM) analyses. The quality of the prepared sources in compliance with regulatory norms were evaluated to ensure their safety during application and found to be satisfactory.

“…Our group have used a novel method to adsorb radioiodine( 125 I) on silver wires, by precoating the wires with palladium [14][15]. The experimental conditions such as amount of radioactivity, carrier concentration, reaction time, reaction temperature, reaction volume, pH of the reaction mixture, etc.…”

“…Sealed sources with the radioactivity of several thousand curies (e.g., 60 Co, 63 Ni, 90 Sr, 137 Cs, 147 Pm, 169 Yb, 170 Tm,192 Ir, and 241 Am) are used in industrial irradiators for production of plastic shrink tubing, flow rate measurements, leak detections, radiography to inspect cracks in steel pipes, radioactive measurement gauges used for measuring liquid and solid thickness, mineral resource evaluation, and food irradiation [2,9]. In medicine, 166 Ho, 144 Ce, 32 P, 133 Xe, 60 Co, 90 Y, 90 Sr, 125 I, and 103 Pd are used in radiation therapy (teletherapy, brachytherapy) for treatment of malignant diseases, bone density measurements, and treatment of brain and prostate cancer [2,10]. Different methods are used for preparing 241 Am, 166 Ho, 137 Cs, 90 Sr, 65 Zn, and 60 Co sealed sources, depending on the radioactivity needed and the purpose of use [2][3][4][5][6][7][8][9][10][11][12][13][14].…”

Poly(acrylamide-acrylic acid)-montmorillonite composite [P(AAm-MA)-M] was synthesized and used for preparing 60 Co, 65 Zn, 134,137 Cs mixed sealed source. The synthesis procedure was based on γ-induced polymerization of polyacrylamide (PAAm) in the presence of acrylic acid (AA), clay minerals (montmorillonite, M), and N,N'-methylenebisacrylamide (NMBA) as a cross-linker. The adsorbent functionality was assayed using FTIR spectroscopy and thermal analysis. The distribution coefficients of 60 Co(II), 65 Zn(II), and 134,137 Cs(I) ions on P(AAm-MA)-M were determined in relation to HCl concentration. P(AAm-MA)-M was loaded with 60 Co, 65 Zn, and 134,137 Cs by equilibrating it (0.5 g) with a mixed solution of 60 Co, 65 Zn, and 134,137 Cs at pH 3 (HCl) for 24 h at 25 ± 1°C. Mixed sealed source containing 5.3, 0.03, 0.05, and 1.05 μCi of 60 Co, 65 Zn, 134 Cs, and 137 Cs, respectively, was prepared by packing 100 mg of the loaded matrix in the cylindrical cavity of a Chinese Artelone capsule. The sealed source was subjected to quality control tests.
