The Italian National Institute of Ionizing Radiation Metrology (ENEA-INMRI) and the Association Medical Physics (AIFM) offer a certified audit service to radiotherapy (RT) centers for reference dosimetry. Audits are provided photon beams in range 6-18 MV including flattening filter free C-arm Linac, CyberKnife TomoTherapy beams. A dosimeter consisting set TLD chips embedded PMMA waterproof holder is used. TLDs calibrated terms absorbed dose water ENEA-INMRI 60Co γ-beam. Correction factors...
The hypothesis that proximity to the Sun causes variation of decay constants at permille level has been tested and disproved. Repeated activity measurements mono-radionuclide sources were performed over periods from 200 days up four decades 14 laboratories across globe. Residuals exponential nuclear curves inspected for annual oscillations. Systematic deviations a purely curve differ one data set another are attributable instabilities in instrumentation measurement conditions. most stable...
Claims that proximity to the Sun causes variation of decay constants at permille level have been investigated for alpha decaying nuclides. Repeated rate measurements 209Po, 226Ra, 228Th, 230U, and 241Am sources were performed over periods 200 d up two decades various nuclear metrology institutes around globe. Residuals from exponential curves inspected annual oscillations. Systematic deviations a purely curve differ in amplitude phase one data set another appear attributable instabilities...
The hypothesis that seasonal changes in proximity to the Sun cause variation of decay constants at permille level has been tested for radionuclides disintegrating through electron capture and beta plus decay. Activity measurements 22Na, 54Mn, 55Fe, 57Co, 65Zn, 82+85Sr, 90Sr, 109Cd, 124Sb, 133Ba, 152Eu, 207Bi sources were repeated over periods from 200 d up more than four decades 14 laboratories across globe. Residuals exponential nuclear curves inspected annual oscillations. Systematic...
the gamma-emitting radionuclide Technetium-99m (99mTc) is still workhorse of Single Photon Emission Computed Tomography (SPECT) as it used worldwide for diagnosis a variety phatological conditions. 99mTc obtained from 99Mo/99mTc generators pertechnetate ion, which ubiquitous starting material preparation radiopharmaceuticals. 99Mo in such currently produced nuclear fission reactors by-product 235U fission. Here we investigated an alternative route production by irradiating natural metallic...
Claims that proximity to the Sun causes variations of decay constants at permille level have been investigated for beta-minus decaying nuclides. Repeated activity measurements 3H, 14C, 60Co, 85Kr, 90Sr, 124Sb, 134Cs, 137Cs, and 154Eu sources were performed over periods 259 d up 5 decades various nuclear metrology institutes. Residuals from exponential curves inspected annual oscillations. Systematic deviations a purely curve differ in amplitude phase one data set another appear attributable...
Abstract Strontium-90 (Sr-90) contamination in food is a major public health issue. Several radiochemical methods are available for the determination of Sr-90. However, application these procedures not focused on solid foods, but only liquid (milk, water, etc.) and environmental matrices, they were fully validated. The aims this work to establish validate fast, sensitive method Sr-90 matrices such as meat dairy products, seafood, vegetables, animal feed, using specific resin extraction...
Abstract When verifying the validity of exponential-decay law through 137 precise decay rate measurement series at various nuclear laboratories, minor violations have been observed in shape annual cycles residuals with different amplitudes and phase shifts. The timing amplitude these deviations compared local weather data it appears that ambient humidity is highly correlated instabilities radioactivity measurements. In fact, when compensating for a linear relationship absolute air, most are...
