236U is used as a signature in nuclear forensic, environmental and oceanographic studies. Its atomic ratio with the most abundant uranium isotope (238U) in environmental and bioassay samples can vary widely from 10-8 to 10-12. Therefore, its full-range measurement is a challenge by conventional radiometric or mass spectrometric methods. Accelerator Mass Spectrometry (AMS) offers...

The anthropogenic radioisotope, Cs-137, is routinely used in oceanographic studies and the monitoring of radioactive contamination. Currently, this isotope is measured radiometrically by observing its characteristic 662 keV gamma emission. In low concentrations, however, this method of measurement can take days per sample. Recently there has been much interest in the measurement of this...

Technetium-99 (⁹⁹Tc) is one of the most important fission products of ²³⁵U (~6% yield). It is a long lived radioisotope (2.11X10⁵ years half-life), which decays by emiting beta radiation. ⁹⁹Tc is of environmental concern because it is very mobile in the environment as Tc(VII) (TcO₄⁻) and can be bio-accumulated in some plants and animals. ⁹⁹Tc can be measured by ICP-MS, but ruthenium (Ru)...

The CALICE Digital Hadron Calorimeter (DHCAL) is a highly-granular 1m$^3$ large
prototype, based on Resistive Plate Chambers (RPCs) with digital readout of
$1 x 1$ cm$^2$ pads. In special tests, 50 of its active layers were exposed to low energy
particle beams, without interleaved absorber plates. The thickness of each layer
corresponded approximately to 0.29 radiation lengths or 0.034...

Instrument calibration is an integral part of many physical and chemical measurement systems. Commonly, instrument response is plotted against a series of known values (standards) of the measurand to establish a calibration line by linear regression. For example, the relationship is established between emitted light intensity versus concentration in Emission Spectrometry, or ion counts...

Canada's Martian spectrometer, the Alpha Particle X-ray Spectrometer (APXS), is a physics-based third-generation chemical analysis instrument carried by NASA's newest rover on Mars. Mounted at the end of the arm of the Mars Science Laboratory rover *Curiosity*, the fourth and most-recent APXS conducts high-precision in situ measurements of Martian rocks and soils, playing a significant role in...
