HHS-OASH-2026-0397-3813 https://www.regulations.gov/comment/HHS-OASH-2026-0397-3813 When I purchased my first mobile telephone, I set it together, switched it on and held it to my ear. Suddenly I recieved an short sharp electric shock in my nose. Wondering I looked for warnings on the packaging. NONE. Later when I began using this very useful apparatus; also held to my head/ear I experienced a certain typ of headache after some minutes of conversation. Aagin no warning on the packet that this could arise. This headache still arises today, 25 yrs later, even if I use handsfree earphones and cable and the telephone at arms length from me. The headache is stronger when the telephone is used in a car. The same type of headache arises for me with Wifi apparatus radiating in indoor rooms. I am an self employed business person and find the phone very useful, but very problematic. No warning comes from manufacturers or radiation authorities here in Sweden. Now I have to avoid towns where 4G + 5G masts are closer and causing stronger emf radiation. I have to carry a emf test meter so as not to be forced to experience the uncomfortable and inhibiting headache which impairs my whole feeling of wellbeing. At home, I cannot sleep in my above-ground bedroom as the radiation level entering into my property from the nearby telecom mast has increased enormously over the years giving me sleep problems. I have to sleep in the cellar. I discovered that there are many others with the same or similar problem with mobile telephone systems and RF/EMF. I find this particularly disturbing that the mobile industry is not subjected the precautionary principle and to providing tests and studies and that clear information is provided to customers. That is not just and honourable business practice neither honourable politics. This undermines my trust in politics and stock exchange companies. That politicians do not represent the peoples health before the profits of the telecom industri investors and make sure safety is first and that new emf technology business must prove the system harmless, especially to children and insects. I have had to inform myself about the state of the research into EMF effects on living organisms, I found that is is massive but always excluded from the mainstream press and authorities are not published or restrictive towards industry. All this amounts to an undermined quality of life. One is ostracised by others who do not experience problems with emf radiation and have never heard that there is a risk. This is not conjusive to an open and healthy society, even within my family. I really wonder if RF/EMF affects younger peoples cognitive abilities and problem solving intelligence? This over and above the effect that due to the lack of practical experiences in growing children when caught for hours infront of telephones and computers whether radiating or not than gaining life experience.
