Note A quick diagnostic test for understanding a particular high-frequency conducted EMI problem (measured by a LISN at the inputs of the power supply) is to twist the output cables of the power supply tightly together (along with their respective return wires). This induces field cancellation (also called flux containment), thus reducing the radiation from the output cables (if present). 

Briefly, the primary mechanism of microwave heating is dielectric loss. The dielectric loss factor (loss factor e") and the dielectric constant ( ) of a material determine the efficiency of heat transfer to the sample. Their quotient "/ ) is the dissipation factor (tan d). High values indicate ready susceptibility to microwave energy. Materials dissipate microwave energy mainly by dipole rotation and ionic conduction. Dipole rotation affects the alignment of molecules with permanent or induced dipoles, with the electric field component of the radiation. 

DSB repair have been conducted at relatively high doses, sufficient to induce substantial cell killing. Conventional methods of detecting DSB repair in vivo, which are based on extraction of DNA and measurement of mobility in pulsed-field electrophoresis, require doses diat induce 100 or more breaks per cell. For the human genome, these correspond to acute doses of approximately 3 Gray (Gy) or more of low-linear energy transfer (LET) radiation (5).
