15 صفحه اولScintillation Proximity Assay on the TopCount Microplate Scintillation Counter
The TopCountTM Microplate Scintillation Counter quantitates radioisotopes by liquid scintillation counting in standard microplate formats. Assays that previously had to be transferred from microplates to vials or to non-standard formats for counting can now be quantitated directly in microplates. TopCount can count up to 12 samples simultaneously with performance comparable to that of discrete ...

15 صفحه اولA coincidence scintillation spectrometer
The coincidence spectrometer consists of two scintillation spectrometers, each of which can be used as either a beta-ray or a gamma-ray spectrometer, depending on what crystals are used. The pulses from the first spectrometer are analyzed with a single channel analyzer. The pulses corresponding to a certain energy are picked out with the analyzer and are fed into one channel of a coincidence ci...
متن کاملAssessment Ofnew Correction Techniques for Faradayrotationand Ionospheric Scintillation: a Biomass Perspective
The European Space Agency BIOMASS mission will use a P-band polarimetric SAR at 435MHz with 6MHz bandwidth to measure above-ground biomass in order to assess the levels of carbon tied up in forests across the globe. It will also be capable of measuring changes in this quantity over its 5-year lifetime. At this wavelength, the ionosphere can strongly affect the signal, the principal effects bein...
