Principles for Non-Ionizing Radiation Protection [PDF]

Health Physics, 2020
Abstract In this statement, the International Commission on Non-Ionizing Radiation Protection (ICNIRP) presents its principles for protection against adverse health effects from exposure to non-ionizing radiation. These are based upon the principles for protection against ionizing radiation of the International Commission for Radiological ...

Non-Ionizing Radiation Measurements for Trajectography Radars. [PDF]

Sensors (Basel), 2022
This work presents a Non-Ionizing Radiation (NIR) measurement campaign and proposes a specific measurement method for trajectography radars. This kind of radar has a high gain narrow beam antenna and emits a high power signal. Power density measurements from a C-band trajectography radar are carried out using bench equipment and a directional receiving

Development of a 6 GHz RF-EMF Exposure System for Investigating Human Skin Temperature Responses: Characterization, Integration, and Pilot Testing

IEEE Access, 2023
We developed a radiofrequency electromagnetic field (RF-EMF) exposure system to investigate human skin temperature responses to localized exposures. The system was designed to project a 6 GHz RF-EMF beam with enough energy to rapidly increase peak local ...

Effect of Dose Irradiation on the Expression of BRCA1 and BRCA2Genes in MCF-10A and MCF-7 cell lines [PDF]

Iranian Journal of Medical Physics, 2023
Introduction: Breast cancer can be caused by a mutation in its genome. Some mutations are cancer-predisposition which exist at the moment of germ cell genesis. It has been discovered that BRCA1 and BRCA2 are linked to hereditary breast cancer.
