Radon Measurement Standards and Calibration

This issue of the Journal of Research of the National Institute of Standards and Technology resulted from a one-half day seminar devoted to descriptions of the current status of the metrology of radon in international laboratories specializing in that area. The seminar, held June 5, 1989, at the Physikalisch-Technische Bundesanstalt (PTB), Braunschweig, Federal Republic of Germany was co-sponso...

A Calibration and Quality Assurance Program for Environmental Radon Measurements

The ideal facility for assessing the quality of radon measurements at environmental levels consists of: (1) an instrument whose response to radon and its progeny is determined from measurements of a certified or standard 226Ra source, and (2) a calibration room with a known radon concentration. The linkage between these two elements and additional quality control requirements are discussed here...

Calibration and Standards in Flow Measurement

Calibration is defined as follows: ‘The set of operations that establish, under specified conditions, the relationship between values of quantities indicated by a measuring instrument or measuring system and the corresponding values realized by standards.’ It is important to recognize at the outset the definition of a ‘calibration’ and to note that the ‘comparison’ applies only to the condition...

Preparation and Calibration of Carrier-Free 209Po Solution Standards

Carrier-free 209Po solution standards have been prepared and calibrated. The standards, which will be disseminated by the National Institute of Standards and Technology as Standard Reference Material SRM 4326, consist of (5.1597 ±0.0024) g of a solution of polonium in nominal 2 mol · L-1 hydrochloric acid (having a solution density of (1.031±0.004) g · mL-1 at 22 °C) that is contained in 5 mL f...

Spectrophotometric calibration system for DECam

We present a spectrophotometric calibration system that will be implemented as part of the DES DECam project at the Blanco 4 meter at CTIO. Our calibration system uses a 2nm wide tunable source to measure the instrumental response function of the telescope from 300nm up to 1100nm. The system consists of a monochromator based tunable light source that is projected uniformly on a Lambertian scree...
