Measurement Science and Technology Paper - Potential for improved radiation thermometry measurement uncertainty through implementing a primary scale in an industrial laboratory
A primary temperature scale requires realising a unit in terms of its definition. For high temperature radiation thermometry in terms of the International Temperature Scale of 1990 this means extrapolating from the signal measured at the freezing temperature of gold, silver or copper using Planck's radiation law. The difficulty in doing this means that primary scales above 1000 °C require ...

What is a Calibration Certificate?
Many of the devices and instrumentation utilized in critical industries are highly sensitive, so sensitive that minor changes in position or environmental conditions can render them useless. Critical devices must be routinely monitored and calibrated against traceable standards to ensure accuracy and minimize uncertainty. It’s important to note that each device is held to its own standard ...

Sample Size for Laboratory Calibration of Subsurface Neutron Moisture Gauges
The estimation of adequate sample size is critical to all laboratory methods of calibration of neutron moisture gauges. Neutron gauge response is a function of the true sample geometry rather than an arbitrarily defined spherical geometry. A two-group solution is obtained for neutron flux in a homogeneous, finite, cylindrical sample. The theoretical flux distributions for this solution and for ...

Profiling OCR in Stiff Clays by CPT and SPT
Standard penetration tests (SPT) and cone penetration tests (CPT) have conventionally been used to index profiles of undrained shear strength su in clay deposits. Since su is related to stress history, an alternative use of penetration resistances is the profiling of in-situ overconsolidation ratio (OCR). An empirical methodology is developed based on compiled data bases from 50 sites ...

An update of the probabilistic safety assessment of the Radiation Monitor Calibration Laboratory of a Brazilian nuclear power station
In 2001, a probabilistic safety assessment of the Radiation Monitor Calibration Laboratory of a Brazilian nuclear power station was performed to estimate its radiological risk. Owing to the lack of data, many conservative assumptions were considered. The purpose of this paper is to obtain the updated laboratory radiological risk. A human reliability analysis of the procedure for calibrating the ...

Thickness and material selection of polymeric passive samplers for polycyclic aromatic hydrocarbons in water: Which more strongly affects sampler properties?
Three configurations of single‐phase‐polymer passive samplers made of polyoxymethylene (POM), silicone rubber (SR) and polyethylene (PE) were simultaneously calibrated in laboratory experiments by determining their partitioning coefficients and the POM diffusion coefficients and by validating a kinetic accumulation model. In addition, the performance of each device was evaluated under field ...
