A survey of the urban radiofrequency (RF) environment.
Radiation Protection Dosimetry, 2014In 1980, Tell and Mantiply published a study of radiofrequency (RF) fields measured across 15 major metropolitan areas in the USA. They required a van fully equipped with instrumentation and computing capability for their measurements. This study aimed to assess whether and how hand-held instrumentation available today would facilitate and enhance the ...

Radiofrequency (RF) Plasma Nitriding
, 2017The usual plasma nitriding is done using glow discharge with the workpiece as cathode at pressures between 100 and 1000 Pa. This procedure leads to bombardment of the surface by energetic ions, therefore the temperature is high.

Complications in Radiofrequency (RF)
, 2012As there is an increasing demand for novel technologies in the field of aesthetics, challenges of the appropriate use of these technologies and safety profiles are important considerations to address. Advances have progressed from the once standard treatments of ablative procedures to the very popular nonablative rejuvenation procedures.

Radiofrequency (RF) Sickness in the Lilienfeld Study: An Effect of Modulated Microwaves?
Archives of Environmental Health: An International Journal, 1998There is a controversy among professionals regarding whether radiofrequency radiation sickness syndrome is a medical entity. In this study, this controversy was evaluated with a methodology adapted from case studies. The author reviewed U.S. literature, which revealed that research results are sufficiently consistent to warrant further inquiry.

Radiofrequency (RF) effects on blood cells, cardiac, endocrine, and immunological functions
Bioelectromagnetics, 2003Effects of radiofrequency electromagnetic fields (RFEMF) on the pituitary adrenocortical (ACTH), growth (GH), and thyroid (TSH) hormones have been extensively studied, and there is coherent research on reproductive hormones (FSH and LH). Those effects which have been identified are clearly caused by heating. The exposure thresholds for these effects in

Investigative Radiology, 2001
To develop an experimental tumor model for RF ablation of breast tumors surrounded by fat and to investigate the minimally invasive treatment of such tumors by saline-enhanced RF ablation monitored by ultrasound (US).Twenty-eight VX2 tumors were implanted into the retroperitoneum of 14 rabbits and monitored by B-mode US at regular intervals of 2 to 3 ...
