We investigated whether domestic and professional induction cooktops comply with the basic restrictions defined by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). Based on magnetic field measurements, a generic numerical model of an induction cooktop was derived in order to model user exposure. The current density induced in the user was simulated for various models ...

introduction the main goal of this study was to perform quality control test on all radiography units operating in golestan province of iran. materials and methods forty-four x-ray units were examined based on general accepted programs for quality control. eight parameters including kvp accuracy, kvp reproducibility, ma-time reciprocity, exposure linearity, exposure reproducibility, timer accur...

The typical radiating power levels of the DVB-H sites are normally between the values used in mobile and television broadcast networks. It is thus important to take into account accordingly the EMC (Electro Magnetic Compatibility) as well as the human exposure limits in the DVB-H transmission facilities. This paper presents a practical method for estimating the safety limits of human exposure a...

The Institute of Electrical and Electronics Engineers (IEEE) Committee on Man and Radiation (COMAR) recognizes that there is public concern about the safety of exposure to the radio frequency (RF) and microwave (MW) fields from hand-held, portable, and mobile cellular telephones. Several national and international organizations have established guidelines for human exposure to radio frequency e...

Abstrac t-The results of a magnetic and electromagnetic measurement survey are presented, which was carried out around a Magnetic Resonance Imaging device. The investigation is performed with the twofold aim of characterising the field source under the different operating sequences and evaluating the exposure of workers both to the static and time-varying magnetic field. The exposure levels are...

Introduction Sulfuric acid was first assessed to be carcinogenic in 1997 in a report of the World Health organization WHO (IARC). Based on this report, the Senate committee dealing with the control of harmful substances in the workplace submitted the first proposal justifying a lower occupational exposure limit [2].This proposal contained a list of many individual studies. In the investigations...

This special issue of Regulatory Toxicology and Pharmacology is devoted to a discussion of the development and regulation of occupational exposure limits (OELs) in Asia. OELs are the necessary links between the science of risk assessment and the management of risk as a result of occupational exposures. Ideally, OELs are based on the best available and most up-to-date information. The developmen...

Occupational exposure limits (OELs) are used as an important tool to protect workers from adverse chemical exposures and its detrimental effects on their health. The Ministry of Labor (MOL) can establish and publish OELs based on the Industrial Safety and Health Act in Korea. The first set of OELs was announced by the MOL in 1986. At that time, it was identical to the Threshold Limit Values of ...
