New approaches in training for in situ visualization of ionizing radiation measurements
Surveying an environment for sources of ionizing radiation requires the use of measurement tools and skills developed from training in order to understand and analyze measurements. Recent advances in technology allow for new approaches to be made in the radiation survey methodology generally used …

The Hemispherical Blackbody (HSBB) for improved traceability of longwave downward radiation
… the detection of atmospheric longwave downward radiation is presented. Key component of this traceability chain is a new reference cavity blackbody, the Hemispherical Blackbody of the Physikalisch-Technische Bundesanstalt. As a result, climate relevant atmospheric irradiance measurements are via …

The variation of components in the radiation balance over different fynbos vegitation types
… consider the vegetation at the sites where the radiation measurements were carried out in order to determine whether similar vegetation structural types have similar radiation regimes. In order to do this, six sites were selected in the Cape of Good Hope Nature Reserve. At each site the …

Development of Measurement Methods for Monitoring the Effects of Shed Fouling in a Fluid Coker Stripper
… to mimic shed fouling. Differential pressure, radiation transmission, and heat transfer measurements were performed above the sheds to assess the effects of fouling. Each measurement technique can detect the changes in hydrodynamics from adding an obstruction to clean stripper sheds. When …

The design of a 1500 curie Co60 teletherapy unit
… healthy tissue is not irreparably damaged. If radiation is directed at the tumor from an external source, there are two procedures which aid in achieving this aim. The first is to use a high energy radiation. This tends to lower the absorption of radiation by tissue between the source and the …
