“…Furthermore, it is also used as the photon source in dual-photon absorptiometry machines to determine the mineral content of bones of osteoporosis patients. Its production feasibility with a high specific activity via the 156 Dy(n, α) 153 Gd reaction was studied [30]. Internal radiotherapy has gained considerable significance in recent years.…”

Development of radiochemistry / Uranium and thorium chemistry / Nuclear reaction cross section / Radioisotope and radiopharmaceutical production / Neutron activation analysis / Separation studies / PINSTECHSummary. With the inception of Pakistan Atomic Energy Commission (PAEC) in 1956, peaceful uses of atomic energy commenced for the benefit of scientific community as well as masses of Pakistan. Radiochemistry played a vital role right from the beginning. The research and development in this field accelerated soon after the criticality of the first research reactor named as Pakistan Research Reactor (PARR-1) at the Pakistan Institute of Nuclear Science and Technology (PINSTECH), Islamabad. The first radioisotope produced at PARR-1 for application in nuclear medicine was 131 I. Later on, many other radioisotopes were prepared and radiopharmaceuticals were synthesised for their use in industry and hospitals. Besides providing pure radioactive tracers for nuclear medicine, radiochemistry also enhanced the detection limit of impurities at all stages of nuclear fuel cycle for power generation. In 1983, research in the field of nuclear data measurement began. The main aim was to identify suitable conditions for the production of radionuclides for cancer diagnostics, treatment and therapy. With the establishment of a second research reactor (PARR-2) at PINSTECH, research in neutron activation analysis, radioisotope production and separation studies gained more momentum and many research articles were published. Solvent extraction, adsorption and ion-exchange were the main routes of separation in those studies. Separation of heavy metals and treatment of waste generated in a nuclear power plant are other important aspects related to environmental restoration and nuclear waste management, where radiochemistry is required. In future, work in radiochemistry will be continued on similar lines to develop novel radiopharmaceuticals, identify indigenous schemes for nuclear waste management and work out intelligent procedures for material characterization for benefit to mankind, especially the people of Pakistan.

“…The relative INAA technique has extensively been used in our laboratory for the analyses of a wide variety of matrices [3][4][5][6]. We report the analysis of high purity gadolinia using radiochemical neutron activation analysis (RNAA) technique for the determination of minor, and trace impurities.…”

High purity gadolinia / Trace impurities / RNAA / INAASummary. Extensive use of gadolinia for different high technology applications such as infrared absorbing automotive glass, petroleum cracking catalyst, gadolinium-yttrium garnets and color TV tube phosphors requires a precise characterization of the material. A radiochemical neutron activation analysis (RNAA) procedure has been employed to investigate 16 trace impurities in high purity gadolinia. RNAA procedure enhanced the sensitivity of the technique. The concentrations of trace impurities ranged from 20 ng/g to 34 µg/g. The impurity contents were found to be low; therefore, their deleterious effects would be negligible.

Activation cross-sections are presented for the first time fornat Gd(d,xn) 161,160,156(m+),154,154m1,154m2,153,152(m+),151(m+) T b, nat Gd(d,x) 159,153,151 Gd and nat Gd(d,x) 156 Eu reactions from their respective thresholds up to 50 MeV. The cross-sections were measured by the stacked-foil irradiation technique and by using high resolution γ-ray spectrometry. The measured values were compared with the results of theoretical models calculated by the computer codes ALICE-D, EMPIRE-D and TALYS (data from TENDL library). Integral yields of the reaction products were deduced from the excitation functions.
