For the purpose of nondestructive measurements hazardous heavy-element-containing substances in soil samples, emerging technique, triple-exposure X-ray computed tomography (CT), is proposed. The use triple exposure (i.e. three different acceleration voltages for tube) improves accuracy identification atomic number a heavy element. With lead as target element, virtual microtomography simulations...
