Health physics poster exhorting respect for—rather than fear of—radiation. (ORNL, 1947) Radiophobia is an irrational or excessive fear of ionizing radiation, leading to overestimating the health risks of radiation compared to other risks. It can impede rational decision-making and contribute to counter-productive behavior and policies.
The evidence, although of mainly low to moderate quality, shows a correlation between heavy screen time and a variety of health physical and mental health problems. [7] However, moderate use of digital media is also correlated with benefits for young people in terms of social integration, mental health, and overall well-being. [7]
A classic Emerson transistor radio, circa 1958. A transistor radio is a small portable radio receiver that uses transistor-based circuitry.Previous portable radios used vacuum tubes, which were bulky, fragile, had a limited lifetime, consumed excessive power and required large heavy batteries.
Mobile radio telephone systems were mobile telephony systems that preceded modern cellular network technology. Since they were the predecessors of the first generation of cellular telephones, these systems are sometimes retroactively referred to as pre-cellular (or sometimes zero generation , that is, 0G ) systems.
It impairs physical and mental health and limits opportunities to live fulfilling lives. [59] A result of depression during adolescence and adulthood may be substance abuse. [59] [60] The average age of onset is between 11 and 14 years for depressive disorders. [60] Only approximately 25% of children with behavioral problems refer to medical ...
The HPA also says that due to the mobile phone's adaptive power ability, a DECT cordless phone's radiation could actually exceed the radiation of a mobile phone. The HPA explains that while the DECT cordless phone's radiation has an average output power of 10 mW, it is actually in the form of 100 bursts per second of 250 mW, a strength comparable to some mobile phones.
Many early studies show that physical activity has positive effects on subjects with mental illness. [45] Most studies have shown that higher levels of exercise correlate to improvement in mental state, especially for depression. [49] On the other hand, some studies have found that exercise can have a beneficial short-term effect at lower ...
Extensive literature has pointed to the strong association of discrimination on mental health and worse psychological wellbeing of individuals – with some studies even suggesting that the role of discrimination on mental health is greater than on physical health outcomes.
