Abstract An enhanced understanding of background gamma radiation is necessary for accurate radionuclide activity quantification. Background spectra are routinely subtracted from samples prepared in known geometries, with data collection time chosen to optimize statistics counting uncertainties. The work presents measured collected inside and outside shields varying geometry composition, showing the effects these on background. Gamma measurements without blank included along different sizes...
Due to heightened fear surrounding the possibility of future terrorism involving nuclear weapons and radiological dispersive devices, compounded by nonroutine power plant releases such as from emergencies or accidents, interest in contamination levels environmental radiation has spiked. This project sought develop a continuously operational radiation-monitoring system, with graphically visualized data easily accessible public. Because this continuing is housed at university facility, it...
Optically-stimulated luminescent dosimeters are capable of being interrogated multiple times post-irradiation. Each interrogation removes a fraction the signal stored within optically-stimulated dosimeter. This loss must be corrected to avoid systematic errors in estimating average series dosimeter interrogations and requires minimum number consecutive readings determine an that is desired accuracy true with statistical confidence. paper establishes technical basis for determining required...
Power-flow studies on the 30-MA, 100-ns Z facility at Sandia National Laboratories have shown that plasmas in facility’s magnetically insulated transmission lines (MITLs) and double post-hole convolute can result a loss of current delivered to load. To study power-flow physics 1-MA, MAIZE University Michigan, planar MITL loads been developed extend into sight for various imaging diagnostics MAIZE. These use 3D-printed dielectric support structures lined with thin foils either aluminum or...
This is the third in a series of four articles giving medical view nuclear war.The first two dealt with explosions and acute radiation sickness.In context power long-term effects environmental contamination by radioactive compounds are causing great concern.In war these relatively much less important.Sources damage from twofold.People who have been exposed to doses initial early fallout but recovered may, nevertheless, suffer their exposure.Those not fallout, however, may be delayed fallout;...
Abstract A large volume gamma spectrometer was designed and constructed to analyze foodstuffs environmental samples having low radionuclide concentrations. This system uses eight 11-cm × 42.5-cm 5.5-cm NaI(Tl) detectors, chosen due their relatively high sensitivity availability arranged in an octagonal configuration. The sensitive of the is ~28 cm diameter ~42 deep. Shielding consists 86-cm square, 64-cm-tall lead brick enclosure with 18-cm-thick walls lined by 0.3-cm-thick copper plates. An...
Power flow studies on the 30-MA, 100-ns Z facility at Sandia National Laborat ories (SNL) have shown that plasmas in facility's magnetically insulated transmission lines (MITLs) can result a loss of current delivered to load. 1 During pulse, thermal energy deposition into electrodes (ohmic heating, charged particle bombardment, etc.) causes neutral surface contaminants layers (water, hydrogen, hydrocarbons, desorb, ionize, and form anode-cathode (AK) gap. 2 Shrinking typical ele ctrode...

A challenge for TW-class accelerators, such as Sandia's Z machine, is efficient power coupling due to current loss in the final feed. It also important understand how losses will scale larger next generation pulsed (NGPP) facilities. While modeling studying these flow it have diagnostic that can experimentally measure plasmas conditions and help inform simulations. The formed region be challenging diagnose both limited lines of sight being at significantly lower temperatures densities than...
