A generic biokinetic model for C-14 labelled compounds
… of its long half life of 5730 years. The current biokinetic model recommended by the International Commission on Radiological Protection (ICRP) is a conservative estimate of how radiocarbon is treated by the human body. The ICRP generic radiocarbon model consists of a single compartment …

Mathematical solutions to problems in radiological protection involving air sampling and biokinetic modelling
… recycling models take a little longer. A biokinetic model for plutonium in man following systemic uptake was developed. The proposed ICRP lung model (1989) was represented by a first order compartmental model. These two models were combined, and the recycling algorithm was used to …

Evaluation Of Prefermentation As A Unit Process Upon Biological Nutrient Removal Including Biokinetic And Wastewater Parameters
… benefits of primary clarification. Finally, some biokinetic parameters necessary to successfully model both the activated sludge systems and the prefermenter were determined and compared for the prefermented versus the non-prefermented system. Important findings developed during the course of this …

An evaluation of Biokinetics internships
… This process evaluation allowed an evaluation of Biokinetic Honours and internships, and how they functioned at a specific moment in time. Descriptive statistics and a chi-square test were used to analyse the quantitative results and Thematic Content Analysis (TCA) was used to analyse qualitative …
