As a radiopharmaceutical, the use of 59 Fe is classified as high pharmaceutical risk product. Therefore, standard reference for activity measurement necessary to ensure its metrological aspect. This paper describes an alternative method primary determination establishing reference. The solution was prepared using two different cocktails and measured by 4 p b (LS)- g counting system digital anti-coincidence with emulated live-time extending dead-time. A final results at time samples series...
We have recently developed a standard step attenuator, composed of 10 steps build-up chain power measurement and operating from MHz to 18 GHz. Each shows nominal attenuation about 9 dB an expanded uncertainty 0.0018 at 30 MHz. The overall system has dynamic range over 90
