research
Tarmo is an environmental health scientist and has been researching electromagnetic fields for 10 years. The main fields of his research are electromagnetic fields, their induced health effects and their risk management. For the past 3 years Tarmo has been involved in European Union's and Estonian electromagnetic fields' legislation analysis and formulation as a national expert.
His recent years in research have focused on mobile communications (mobile networking) risk management issues. Tarmo's previous research has also included lighting and optical radiation.
Research areas:
- new electromagnetic fields' legislation, EU directive, national legislation, companies' readiness, legislation impact analysis;
- electromagnetic fields in the work environment: static, low, intermediate and radiofrequencies, their propagation and mitigation, risk analysis, measurements;
- electromagnetic characterization of materials: testing materials for their electromagnetic properties: measuring and calculating reflectivity, transmission and absorption; developing microwave absorption materials;
- the effects of electromagnetic fields on human, cognitive and workability, autonomic nervous system (HRV - heart rate variability); inspiring workers to perform better by using specific electromagnetic signature;
- electrotherapy, pulsed electromagnetic field therapy (PEMF), Transcranial magnetic stimulation (TMS), stimulation current thearpy, shortwave therapy, high frequency therapy, microwave therapy etc.;
- human bioelectrical parameters as stress indicators (skin conductivity, body potential, body currents, biomagnetic and bioelectric field); millimeter waves;
- temporal and spacial fluctuations in Earth's magnetic field; magnetic storms, electro-telluric signals; Schumann resonance;
- ergonomic lighting (spectrum, color temp., flicker and dynamic lighting); improving workers well-being and productivity;
- optical radiation (Ultraviolet, laser- and infrared radiation);
- cognitive ergonomics, the effects of environment and personal traits on environmental sensitivity (including perceived effects from electromagnetic fields); interpreting subconsciousness by endogenous signals; sensitivity of human being to weak external factors.
Tarmo's hobbies include electronics and electrical engineering, which have resulted in several advantageous technical solutions for his research.

research inventory
The inventory provides capabilities to measure from static to super high frequencies (ITU bands: TLF, ELF, SLF, ULF, VLF, LF, MF, HF, VHF, UHF, SHF up to 40GHz). Also visible light characteristics, ultraviolet radiation (UV-A, UV-B, UV-C separately) are measurable. Electromagnetic fields measurements are capable of registering short pulses (e.g. wireless data transmissions), RMS-mode and peak-mode, also time series measurements (time averaging), logging and spectrum measurements.
