Question

Dielectric heating of WPM uses which of the following methods to treat the wood?
Microwaves or kilns
Radio frequency or fumigation
Microwaves or pressure treating
Microwaves or radio frequency

Answer 1

Dielectric heating of wood-based materials (WPM) typically involves using **microwaves or radio frequency** methods. These methods generate heat internally within the material, leading to efficient drying or treatment. So, the correct answer is:

**Microwaves or radio frequency**.
