Introduction: New technologies employing radio frequency (RF) emissions are constantly emerging. Some of them employ frequencies and pulse characteristics that have not been well studied for their effects on biological material. Bioeffects research is required to determine the hazard thresholds and interaction mechanisms of such emissions and address the appropriateness of current health and safety standards. Additional data may indicate that current standards are lax and permissible exposure limits (PEL) need to be reduced; or they may indicated that current standards are unnecessarily restrictive and the PEL can be safely raised. This paper concerns recent bioeffects research on two types of emissions: (a) High Peak-Power Low Average-Power Pulses, including Ultrawideband Pulses (
