iation Safety Officer Course Module 1.1 – Basic Mathematics
OVERVIEW
This module is intended to provide you with the information and skills you will need
to carry out the basic mathematics calculations in subsequent modules. An ability
to manipulate numbers and equations successfully is important as it will help you
to assess hazards arising from the use of sources of radiation. It is also important
that you are able to use graphical methods to analyze measurement data, and that
you can extract correct information from published graphs. An understanding of
counting statistics will allow you to quantify the accuracy of the measurements that
you have taken and help you to assess the level of hazard in the workplace.
LEARNING OBJECTIVES
When you have completed this module you will be able to do the following:
1) Interpret numerical data to appropriate levels of accuracy.
2) Use rounding correctly to produce sensible results.
3) Use symbols to represent values in order to solve problems.
4) Manipulate algebraic symbols in formulae.
5) Use scientific notation to express large and small numbers simply.
6) Perform simple calculations using numbers expressed as bases and
powers.
7) Perform simple calculations using common logs, natural logs and
exponentials.
8) Draw graphs with linear and log scales.
9) Obtain data from graphs.
10) State the significance of the area under the curve.
11) Explain how probability indicates the chance of an event occurring.
12) Calculate errors on a set of numbers.
