Naturalist

Not surprisingly, some aspect of the natural sciences will run through the Naturalists interests - from ecological awareness to nutrition and health. People with an interest in horticulture, land usage and farming (including fish) are Naturalists.

Some Naturalists focus on animals rather than plants, and may enjoy working with, training, caring for, or simply herding them. Other Naturalists will prefer working with the end result of nature's produce - the food produced from plants and animals. Naturalists like solving problems with solutions that show some sensitivity to the environmental impact of what they do. They like to see practical results, and prefer action to talking and discussing.

The Work header image

Non-destructive testing specialists examine vitally important structures and vehicles, including aircraft, trains, bridges and pipelines. They use non-destructive testing methods (NDT), which means that after specialists have tested a component it remains useable.  
 
Non-destructive testing specialists look for signs of corrosion, metal fatigue, cracks and other flaws. NDT is essential for safety; specialists may also use it to improve output or profitability, for example, to make sure an oilrig is working safely and at full capacity.  
 
There are many different methods of carrying out NDT. The original method is a visual examination. With advances in technology, NDT specialists can now examine structures and components by using lenses, closed circuit television and fibre optic devices. This technology enables specialists to examine structures on the seabed, or look at components in a radioactive environment.  
 
In liquid penetrant testing, the most common type of NDT, specialists coat an object with a visible or fluorescent dye. Any cracks in the surface will draw in the dye. After cleaning away excess penetrant, NDT specialists use a developer (which acts like blotting paper) to draw the dye back up, therefore revealing the crack.  
 
Non-destructive testing specialists can use radiography to produce an image of an object on a film. For example, they may use X ray or gamma radiation to look for internal defects in metal castings.  
 
They may also use ultrasonic to detect faults in solid materials. This follows a similar principle to that used in sonar equipment at sea. NDT specialists introduce sound into the test object. By looking at how the sound travels within the object, they can map the presence of imperfections (which might bounce the sound around). They use ultrasound to examine welds in nuclear reactors, and in medical imaging studies. 2 other methods are using eddy current and magnetic particles.  
 
NDT is a very fast-moving area; specialists are developing and using new methods all the time, like acoustic emission (which 'listens' to the growth of a crack), leak testing and thermography (used to analyse temperature data).  
 
Specialists often develop expertise in one or two methods of NDT, but they need to know how to interpret all methods. They also need to develop an understanding of the manufacturing processes they are involved in, to predict the type, position and effect of faults.
