30. Modelling Indoor Radon Through Dimensional Analysis BY Dawodu G. A. and Mustapha A. O. Transactions of NAMP Volume 5,(September and November, 2017), pp 231 – 240
Sale price: $5.00


Dimensional analysis (DA) is frequently used by engineers and physicists to reduce the complexity of fundamental equations describing the behaviour of a system to the simplest and most economical form. This work proposes a refinement to an approach in the traditional paradigm for carrying out DA. The said refinement will enable the researcher to obtain some graphical displays that will enable him/her to predict, as accurately as possible, a functional relationship existing between the dependent and independent variables that are involved in a Buckingham -theorem. With our technique, attempts to derive a model through which the rate of emission of indoor radioactive radon can be estimated have now materialized. In this article, we first provide an overview of DA and give basic recommendations for designing DA experiments. Next, we illustrated the use of technique and concluded by the fitness of our derived model. Radon is a radioactive gas whose effect on residents has not been adequately studied. This attempt is geared towards being able to quantify the average emitted radon for some common domestic household types (in the present case, a duplex building) in an averagely populated area.
