Comparison of (18)F activity measurements at the VNIIM, NPL and the ENEA-INMRI using the SIRTI of the BIPM.

In 2014, the first three comparisons of activity measurements of (18)F were carried out at the VNIIM, NPL and the ENEA-INMRI using the BIPM's Transfer Instrument of the International Reference System. The transfer instrument and the NMIs primary measurement methods are briefly described. The degrees of equivalence with the key comparison reference value defined in the frame of the corresponding SIR comparison have been evaluated.

[Synthetic transformations of higher terpenoids. XXVI. 16-Acetylaminomethyllabdanoids and theirs cytotoxicity].

Condensation of methyl 16-aminomethyllambertianate with N-Boc-omega-amino acids leads smoothly to 16-(N-Boc-aminononan)- and 16-(N-Boc-aminoundecan)amidomethyllabdanoids. The amide of bicyclo[2.2.

Some examples of the MRA application in trading of radionuclide products and radioecological monitoring.

Three examples of bilateral cooperation connected with trading of radionuclide products and radioecological monitoring, are discussed. The example in the field of trading is related to the shipment of Russian sources with a high specific activity of 60Co applied for radiation therapeutics to the UK. The examples in the field of radioecological monitoring concern the establishment of equivalence between the 235U reference standards used in Russia and the USA to classify SNM monitors and ensure radiation safety at salvage of the "Kursk" nuclear-powered submarine.

A source for measurement of the absolute intensities of 226Ra gamma-radiation in equilibrium with decay products.

The design and production techniques of a gamma-ray spectrometric source of 226Ra in equilibrium with its daughter decay products have been developed. The radon emanation coefficient of the source did not exceed 0.1%.

[Thoracoabscessotomy in combined treatment of lung gangrene].

Patients with gangrene and gangrenous abscess of the lung belong to the most severe group of patients with purulent lung diseases. Conservative treatment is not effective, lethality after lung resection or pneumonectomy ranges from 20 to 70%, therefore the study of less traumatic but life-saving operations is topical. From 1996 to 1998, 296 patients with purulent destructive processes in the lung were hospitalized, 34 of them had gangrene or gangrenous abscess of the lung with significant intoxication.
