ICNIRP's latest guidelines for limiting radio frequency exposure have been published

International Commission on Non-Ionizing Radiation Protection, ICNIRP, updated in March guidelines for protection against radiation on the radio frequencies. This update was published following a public consultation process that began two years ago. The Tnuda Center submitted its comments in the course of this process.

The Institute of Electrical and Electronics Engineers (IEEE) Published an Updated Version of International Standard for Safety of Human Exposure to Non-Ionizing Radiation

The Institute of Electrical and Electronics Engineers (IEEE) published an update to the international standard for safety levels with respect to human exposure to non-ionizing radiation (electric, magnetic and electromagnetic fields) in the range of 0-300 GHz.

Reviewing and Mapping the Sources of Non-Ionizing Radiation Exposure in the Student Environment

Since 2011, the National Information and Communication Technologies (ICT) Program "Adjusting the Education System to the 21st Century" is gradually being implemented in Israeli schools. The program deploys the basic infrastructure that enables the use of advanced technologies in teaching, learning and evaluation (TLE) in a school environment. This infrastructure includes: broadband Internet, projector in every classroom, teacher laptops, classroom sound system, and means of darkness. The use of some of the program-required technologies is accompanied by exposure to non-ionizing electromagnetic radiation (RF) and low frequency electric and magnetic fields. In addition, in the student vicinity there are non-ionizing radiation sources (RF and electric and magnetic fields) due to personal devices such as mobile phones and tablets.

Given the current scientific knowledge, it is agreed that exposure should be reduced using the precautionary principle. This principle is especially valid in children considered populations at risk.

Therefore, in the following article, we have concentrated on the sources of radiation exposure in a school environment, with reference to their different characteristics, their use in the classroom, and their impact on the student's exposure to radiation.

 

Internet of Things (IoT)

 

       
 

  • The term "Internet of Things" (IoT) refers to a very wide range of devices and appliances that are capable of connecting to the Internet, in the individual & home environments, in public space and workplaces

  • "Smart home", "smart city", and "smart shopping" are examples of technologies based on the Internet of Things

  • It's estimated that the Internet of Things will be widely implemented and change many aspects of our lives

 

  
       

 

Low Frequency Range

  • Low frequency range refers to the lower end of the electromagnetic radiation spectrum and includes the Extremely Low Frequency (ELF), which ranges from 3 Hz to 30 Hz, and Super Low Frequency (SLF), which ranges from 30 Hz to 300 Hz.
  • Within this frequency range, electric field and magnetic field behave more independently, so exposure to an electric field and exposure to a magnetic field is usually considered separately (rather than exposure to electromagnetic radiation).
  • The main exposures at low frequencies occur in fields generated near electric grids, electrical infrastructure in the buildings and in the proximity of electrical and electronic devices (in Israel, the frequency of the electric grid is 50 Hz).
  • Additional exposures within this frequency range are from electric public transportation and electric vehicles, occupational exposures, medical equipment, and more.
  • In 2001, the International Agency for Research on Cancer (IARC) decided to classify magnetic fields at the frequency of the electric grid. Possibly carcinogenic to humans (Class B2).
   

 

Electric and magnetic fields produced by electric grids as well as electrical and electronic devices surround us wherever modern life exists. The range of uses of electricity from electricity grids is endless. Nowadays, we can no longer imagine life without the use of electricity. Therefore, it is important that we become better acquainted with the sources of those fields, their physical characteristics, their impact on health, and recommendations to reduce exposure

Health Effects of Exposure to Ultraviolet (UV) Radiation

 

 
  • Sunlight and its heat are essential to most of the familiar life forms. Exposure to UV radiation helps to create vitamin D in the body, which is essential in preventing disease. This radiation may also have a positive effect on skin diseases of various kinds, such as psoriasis and eczema
  
         
 
  • The harmful health effects of exposure to UV radiation include burns, accelerated aging of the skin, development of cataracts, damage to the conjunctiva, and various skin tumors (including malignant melanoma)
  
  • The highest personal exposure to UV radiation from an artificial source is sun beds. In 2009, the International Agency for Research on Cancer (IARC) classified UV-emitting tanning devices as 'carcinogenic to humans'
  

 

The TNUDA Information Center has published updated Recommendations for Educated Use of Cellphones

In light of the time that passed since the publication of the Recommendations for Educated Use of Cellphones (2008) and the increase in the use of devices emitting RF radiation in the general public, as well as the change in technology and usage patterns, the TNUDA Center updated and expanded the existing recommendations.

The World Health Organization publishes new guidelines for kids under the age of five: less screen time, more physical activity, and maintaining sleep time

According to new guidelines issued by the World Health Organization (WHO) in April 2019, kids under the age of five are advised to reduce the screen time and duration of their stay in trolley and baby seats. In addition, the recommended number of hours of sleep should be strictly observed for these ages and more time for active play with their parents should be made.

The OECD published a final report on the impact of the use of technology on the brain, cognition and well-being in children

In its report, the Organization for Economic Co-operation and Development (OECD) reviewed the existing scientific literature on the effect of the use of technology on children's brains and their emotional, social, cognitive, and physical development. In addition, the report examined whether national guidelines and existing recommendations in different countries are based on accumulated scientific knowledge.

Diode

An electronic component allowing electric current flow in one direction only. A diode is formed at an intersection of two types of materials (semiconductors). The importance of using diodes in electronic circuits is in their combination with an alternating voltage source.
