"ไม่มีหลักฐานว่า สัญญาณ Wi-Fi จะเป็นอันตรายต่อสุขภาพครับ"

มีเพื่อนส่งข่าวนี้มาให้ดู (จาก https://www.facebook.com/JeenThaiNews/posts/239698794468233) ว่า "มีชายชาวเมืองชิงเต่า ประเทศจีน เขียนกระดาษโน้ต ร้องขอเพื่อนบ้านที่อยู่ชั้นบน ให้ปิดสัญญาณ Wi-Fi เนื่องจากกังวลว่า รังสีจะส่งผลกระทบต่อทารกในครรภ์ของภรรยาเขา ... จนเพื่อนบ้านต้องเขียนตอบกลับว่า จะไม่ปิดเพราะต้องใช้เรียนออนไลน์ ถ้าไม่พอใจ ก็ย้ายออกไปซะ"

อ่านแล้วก็ขำ ปนเห็นใจ ว่ายังมีคนอีกเป็นจำนวนมากแน่ๆ ซึ่งรวมถึงคนไทยด้วย ที่เชื่อว่า "สัญญาณ Wi-Fi นั้นเป็นอันตรายต่อสุขภาพ" ทั้งที่ไม่ได้มีหลักฐานอะไรยืนยันความเชื่อแบบนั้นเลยนะ

ลองมาดูข้อมูลเรื่องนี้กันนะครับ

1. เดี๋ยวนี้ Wi-Fi ถูกนำมาใช้กันอย่างแพร่หลาย เพื่อให้เครื่องใช้อิเล็กทรอนิกส์ต่างๆ สามารถเชื่อมต่อกับเครือข่ายคอมพิวเตอร์แบบไร้สาย ผ่านสัญญาณคลื่นวิทยุ ตัวอย่างเช่น เราใช้คอมพิวเตอร์แล็บท๊อปต่อเชื่อมกับอินเตอร์เน็ตผ่านกล่องรับส่งสัญญาณ wi-fi ในบ้าน ในโรงเรียน หรือตามสถานที่สาธารณะ

2. ซึ่งถ้าใครอยู่ในบริเวณที่มีสัญญาณ wi-fi ก็เสมอกับกำลังได้รับ "พลังงานจากคลื่นแม่เหล็กไฟฟ้าในช่วงความถี่วิทยุ (RF EME หรือ radiofrequency electromagnetic energy)" ในปริมาณน้อยๆ อยู่ตลอดเวลา จนทำให้หลายคนเกิดความกังวลขึ้นมาจะเกิดผลกระทบต่อสุขภาพจากการปลดปล่อย RF EME นี้หรือไม่

3. ระดับของการปลดปล่อยพลังงาน RF EME จาก wi-fi และอุปกรณ์สื่อสารไร้สายต่างๆ นั้น จะถูกควบคุมตามกฏเกณฑ์มาตรฐานขององค์กรที่รับผิดชอบด้านนี้ของแต่ละประเทศ (เช่น ของไทยก็คือ กสทช.) ซึ่งจะกำหนดให้ต่ำกว่าระดับที่จะมีสิทธิก่อให้เกิดอันตรายได้ เพื่อครอบคลุมความปลอดภัยต่อสุขภาพของประชาชนทุกเพศทุกวัย

4. ปรกติแล้ว จุดกระจายสัญญาณ wi-fi และอุปกรณ์สื่อสารที่ใช้ wi-fi จะมีกำลังในการรับส่งสัญญาณต่ำมาก คือแค่ประมาณ 0.1 วัตต์ (หรือเท่ากับ 100 มิลลิวัตต์) เท่านั้น

5. และหลายคนก็มักจะกลัว wi-fi เพราะคิดว่ากล่องเร้าเตอร์นั้น จะรับ/ส่งคลื่นสัญญาณออกมาอยู่ตลอดเวลา แต่จริงๆ แล้ว มันจะรับ/ส่งสัญญาณแค่ประมาณ 0.1% ของช่วงเวลาที่มันทำงานเท่านั้น หรืออาจจะมากขึ้นถ้าคุณกำลังสตรีมวิดีโอดูอยู่สดๆ แต่ยังไง ส่วนใหญ่แล้ว กล่องเร้าเตอร์นั้นมันจะไม่ได้ทำงานอะไร แค่พักระบบไว้รอให้มีการสั่งการให้รับ/ส่งสัญญาณ

6. ยิ่งไปกว่านั้น ยิ่งเราอยู่ห่างจากกล่องเร้าเตอร์ wi-fi ออกไป ระดับของคลื่นที่เราจะได้รับเข้าสู่ร่างกายนั้นก็ยิ่งน้อยลงอย่างมีนัยสำคัญ ... หรือจริงๆ โทรศัพท์มือถือของเรา ยังส่งคลื่นสัญญาณอย่างต่อเนื่อง เป็นปริมาณที่มากกว่า Wi-fi เป็นร้อยๆ เท่า แถมโทรศัพท์มือถือยังอยู่ติดชิดกับศรีษะของเราด้วย แต่ก็ไม่พบว่ามีหลักฐานยืนยันถึงอันตรายต่อสุขภาพจากการใช้โทรศัพท์มือถือ

7. องค์การอนามัยโลก (World Health Organization หรือ WHO) ก็ยืนยันเช่นกันว่า ไม่มีหลักฐานทางวิทยาศาสตร์ที่น่าเชื่อถือ ว่าสัญญาณ wi-fi จะมีผลกระทบใดๆ ต่อสุขภาพ (ถ้าไม่เกินระดับมาตรฐานที่กำหนดไว้)

8. ถึงกระนั้น ถ้าดูผลการศึกษาในสัตว์ทดลอง (เช่น หนูทดลอง) ที่ได้รับคลื่นแม่เหล็กไฟฟ้าจากสัญญาณวิทยุนี้เป็นปริมาณมากๆ ในระยะเวลายาวนาน พบว่าสามารถเพิ่มความเสี่ยงในการเกิดเนื้องอกในสมองได้ จนทำให้ WHO เองจัดให้คลื่นพวกนี้เป็น "สารที่อาจจะก่อมะเร็ง" (แปลว่า ยังไม่มีหลักฐานเพียงพอที่จะฟันธงว่า มันก่อมะเร็งจริง)

9. อย่างไรก็ตาม ปริมาณของคลื่นที่ใช้ในการทดลองกับหนูนั้น มีค่าสูงเกินกว่าระดับที่มนุษย์เราใช้ในโทรศัพท์มือถือหรือเครือข่ายอุปกรณ์ไร้สายมากมายนัก และผลการทดลองในสัตว์ก็ไม่ได้จะสามารถเอามาตีความว่าจะเกิดขึ้นในคนได้โดยตรง

10. ดังนั้น ถ้ายังมีความกังวลเกี่ยวกับเรื่อง wi-fi ก็สามารถลดระดับของการรับพลังงาน RF EME จากการอยู่ให้ห่างจากอุปกรณ์เครื่องมือ wi-fi และลดช่วงเวลาในแต่ละวันที่ใช้อุปกรณ์ wi-fi ลง หรือแม้แต่ปิดอุปกรณ์รับส่ง wi-fi เสียเมื่อไม่ได้ใช้แล้ว

Saya percaya orang ke bulan?

Kisahnya, Saya bukan Ustaz tapi paling banyak orang tanya bab agama, saya okey jer sebab agama ni tanggungjawab kita semua, mana yang boleh saya jawab, saya cuba, yang tak boleh saya senyap, tapi ada jugak tanya tentang SAINS, dan kali ni bab manusia ke bulan.

Ok, saya jawab setakat yang boleh saya jawab

Soalan 1:

“Bro, jika benar orang ke bulan, kenapa sekali jer America hantar orang ke sana, lepas tu dah tiada sape sape yang pergi?”

Hamka said: Nampak sangat tak ikuti perkembangan dunia, tapi ada hati berlagak pandai, siapa bagitahu kau sekali sahaja orang ke bulan?, Sudah enam kali orang ke bulan bang dan jumlah orang pijak kaki ke bulan seramai 12 orang, sebab tu bila orang cakap, gambar ni tipu, saya tanya balik, ni pendaratan yang ke berapa?, lepas tu orang tu cakap, eh, bukan sekali jer ker orang ke bulan, aduh? Orang dah bicang teknik manusia nak ke marikh, dia ke bulan pun belum boleh hadam

Soalan 2:

“Pada pendapat saya yang tak berapa cerdik ini,..,adapun manusia ke bulan cuma dogma orang amerika saya kira...., logiknya kalau dari bumi ke bulan kene guna roket 1000 tan dgn bahan api yang banyak...macamana diorang dari bulan nak kebumi cuma guna shutle yang kontot tu....cerciter2...sembang ringan2 dahlah.”

Hamka said: Bicara ringan sudah.., angkasa adalah vakum, tiada udara, sekali tujahan, lepas tu tutup enjin, maka kau akan bergerak selamanya selagi tidak berlanggar, atau di tarik oleh graviti planet terdekat, cuba tengok tahi bintang bergerak berjuta batu, ada pakai minyak? ini adalah bicara ringan, dan benda ni paling simple bab angkasa, dan jika benda ni fail, langung tak layak nak nafikan sains dan angkasa., ni ringan dah ni, he he he

Soalan 3:

“Kalau dtg bulan boleh pacak bendera?”

Hamka said: “Nabi tak larang nak bermesra dengan bini datang bulan, jadi nak pakac bendara buat apa?”

Soalan 4:

“Tak de org pernah smpai ke bulan..yang ada tu sekarang hanyalah rekaan semata-mata..... benda ni di reka oleh Amerika untuk memenangi perang sains antara Russia.. ia dirakam dalam studio y di rahsiakan.. dari kecil kita di tipu..... jikalau betul org pernah sampai di bulan kenapa negara lain yang maju dah tak pergi?”

Hamka said: “Siapa cakap tak pergi? Ni mesti banyak membaca blog politik hingga lupa nak baca akhbar perdana, korang tahu tak? pada tahun 2008, jepun punya NASA yang dinamakan (JAXA) Japan Aerospace Exploration Agency telah hantar satelit ke bulan yang dinamakan Kaguya atau SELENE yang mana google moon tu ambik dari satelit inilah, lepas tu satelit tu ambil gambar tapak neil amstrong mendarat dan buktikan memang manusia telah ke bulan, lepas tu 2010, china pulak hantar satelit dan buktikan orang dah mendarat ke bulan.., boleh baca berita jepun dan china jika rajin, jika malas dan hidup nak dengki kejayan orang kapir sampai mati, tak dapatlah den nak nolong.., :)

Satu lagi, pernah saya tunjuk link dari laman web negara lain yang buktikan orang ke bulan, kat sorang islam yang dengki dengan kejayaan orang kapir, dia boleh cakap, amerika telah rasuah jepun dan cina untuk tipu nampak gambar kesan pendaratan di bulan, sayapun mintak bukti kat mana kau tahu amarika rusuah dan berapa juta?, dia cakap, naluri dia yang berbisik begitu, HA HA HA.., mundurlah budak sekolah masa depan jika dapat cikgu bodoh sombong. islam ugama yang mementingkan fakta, tak percaya kaji bab hudud, semua kena ada bukti, bukan ikut naluri.., adohai..

Soalan 5:

“Bro, Ustaz azhar idrus cakap Amarica tipu dan telah saman laman web yang membongkar penipuannya, jawab sikit, ni ulamak ni, ulamak mana cakap tipu,” http://www.youtube.com/watch?v=7DdbTx-qrlY

Hamka said: “Nabi dah pesan, jika tak tahu, tanya kepada yang tahu, rujuk an-Nahl: 43, ustaz azhar ni tak tahu pasal sains, bila orang tanya pasal sains, ustaz azhar ni (saya sangka baik) nak perli orang yang bertanya dengan bagi hujah yang kelakar, seperti: “mengikut ulamak arab”, (saya dah gelak, sebab kelakar, kerana bab sains rujuk ulamak arab, ha ha ha, tapi kamu tak faham lawak ustaz ni), satu lagi bila ustaz cakap, “Amarica telah saman laman web yang membongkar penipuannya”, saya gelak berdekah, sebab kelakar, mana ada orang yang menipu saman orang yang membongkar penipuan?, sepatutnya orang yang membongkar penipuan saman si penipu, lawak kan?, tapi kamu tak paham lawak ustaz ni, lalu ustaz tu bagi final lawak, “waktu kapal angkasa turun, kamera dah ada kat bulan ambil gambar” saya gelak berguling guling sebab lawak ni paling lawak, tapi saya rasa kamu tak faham lawak ni, lalu terpaksa ustaz azhar idrus ‘stereotype’kan lawaknya dengan menambah, “bila masa TV3 ambik gambar di bulan?” barulah korang gelak sebab ada perkataan TV3., lepas tu Bob lukman buat lawak pergi waktu malam ke matahari, lambat jugak korang gelak, kena berpikir dulu... aduh!

Soalan 6:

“Bro hamka, saya mushkil, macam mana kapal angkasa nak bergerak ke bulan sedangkan di angkasa tiada udara? Jika kapal terbang, api tolak udara, kapal terbang naik, di angkasa, nak tolak apa? Patut kapal angkasa statik, lepas tu lagi, macam mana api boleh ada di angkasa sedangkan syarat api terbakar perlu kepada oksigen, angkasa, mana ada oksigen? Cuba jawab wahai blogger keretamayat yang perasan pandai sains.”

Hamka said: ni nak cerita balik tentang hukum newton kedua dan inersia, tapi tak payah, bicara ringan sahaja, paling simple kau tengok orang tembak pistol, lepas peluru keluar, bahu akan tertolak ke balakang, bahu tertolak ke belakang adalah disebabkan letupan atau daya tujahan yang keluar dari pistol, bukan disebabkan peluru berlanggar dengan udara, jika kau menembak dalam ruang vakum pun, bahu akan tertolak ke belakang, inilah yang berlaku di angkasa, yang mana gas pada ekor kapal angkasa akan ‘meletup’ dan menolak kapal angkasa bergerak, tentang api di angkasa, dalam gas tu sendiri dah ada oksigen.

Soalan 7.
Mungkin abang hamka boleh jelaskan kpd sy apa maksud ayat ini.., ayat ni cerita tentang bukti, orang tidak boleh ke bukan: rujuk: Quran 55 : 33 “Wahai sekalian jin dan manusia! Kalau kamu dapat menembus keluar dari kawasan-kawasan langit dan bumi (untuk melarikan diri dari kekuasaan dan balasan Kami), maka cubalah kamu menembus keluar. Kamu tidak akan menembus keluar melainkan dengan satu kekuasaan (yang mengatasi kekuasaan Kami; masakan dapat)!
Hamka said: “jangan tafsir Al quran ikut kepala yang suka dengki, nanti masuk neraka, ayat ni tak menggambarkan langsung orang ke bulan,bebaru ni Syed Muzafar pergi ke angkasa tu tipulah ye, sebab dah menembusi atmosphere.., berdosa tafsir Al quran tanpa ilmu, ustaz azhar idrus cakap, manusia boleh pergi ke bulan, takde larangan pun, cuma dia tak percaya.., benda kecik jerpun, tapi bodoh ni benda besar jugak.

Soalan 8:

“Pendpt sy, kalau waktu dulu, mustahil, tipu . memang ada bukti diorg tunjuk tp pada sy mustahil untuk waktu tu, tp sekarang mungkin tak mustahil, ini pendapat sayalah.”

Hamka said: “dik, dulu nak menipu susah sebab belum ada CGI dan nak buat stadio ruang vakkum dulu susak jugak, so.., pada pendapat saya pulak: Sains ni orang tak bagi pendapat, orang buktikan ujikaji, jadi tak payah bagi pendapat bab sains. baik bagi pendapatan kepada sains supaya mereka boleh buat ujikaji dan selamatkan ummat manusia dari kejahilan.., chewah, : )

Soalan 9:
satu je kemusykilan.... kalau tahun 1969 dah sampai bulan, saya rasa dengan kecanggihan ilmu sekarang ni, patutnya dah ada McD kat sana sekarang. Tapi kenapa kerajaan amarica dah tak nak pergi lagi?

Hamka said: Kemusykilan kau tu simple sahaja, zaman dahulu upah engineer tak sampai dua ribu sorang, sekarang, upah technician NASA pun dah 10 ribu, belum masuk kos insurans lagi, baru ni nak naik soyuz pun kena beli 20 biji sukoi baru boleh tumpang.... jadi, belajarlah jugak ekonomi jika nak komplen bab sains.

Soalan 10:

“Orang ke bulan tu terang terang menipu, tak terbakar ke? Sebab permukaan panas kerana dekat dengan matahari?”

Hamka said: dik, suhu panas sebab ada udara, kat bulan takde udara.., jika nak kira dekat dengan matahari, cuba adik naik gunung kinabalu tak pakai baju, sebab gunung tinggi dekat matahari tak payahlah pakai baju, akan mamposlah kesejukan kerana atas gunung ada salji, (tapi memang panas pun suhu bulan, sebab tu design baju angkasawan macam warna periuk-)

Soalan 11.

Bang, saya sokong abang, tapi muskil, bagaimana orang dibulan boleh telefon di bumi, bukan kena ada udara baru boleh?”

Hamka said: mereka guna ;”electromagnetic radiation analogous to visible light, (gelombang frekuency) sebab tu boleh dihantar melalui vakuum, jangan ponteng kelas sains.”

Soalan 12:

Bang, macam mana ada tapak kaki dibulan, bukankah graviti sana rendah?

Hamka said: “kau ambil bedak, kau tabur dalam baldi sampai penuh baldi, lepas tu kau suruh anak kau kau pijak slow jer, ada kesan tak? Tentulah ada sebab yang dipijak tu debu di bulan, bukan pijak batu.eh?, macam mana kau tahu graviti kat sana rendah?, ni mesti orang balik dari bulan bagitahu ni.., hihihi.”

Soalan 13:

“Sy minat juga baca blog abang kadang2.. sy suka quotation abang yakni "semua orang akan menjadi mayat, anda tidak mampu mengubahnya". Tapi Jangan sewenang-wenang mengecop orang lain bodoh seandainya kita tidak benar yakin akan sesuatu hal. Lainlah abang sendiri dah mendarat di bulan. Saya hanya percaya kpd abang Hamka apabila abang sendiri dah pergi mendarat di bulan..

Hamka said: “ok”

Kesimpulan:

Untuk membolehkan manusia ke bulan, Allah tak perlu hantar walaupun seorang Nabi, tapi untuk bina IMAN dalam hati manusia, Allah hantar 124 ribu para Nabi dan rasul…, renung renungkan, dan selamat beramal. :)

到底5G網絡有陰謀論嗎?

[警告] 大家對5G網絡的誤解
5G網絡/信號塔會否危害你健康?
[警告!!!] 5G網絡會否危害你健康?
5G網絡會危害你健康嗎?
解釋你對5G網絡的誤解
5大你對5G網絡的誤解
五個你對5G網絡的誤解

有一件關於我自己的真相要跟大家講. 有時...夜晚...身邊沒有人的時候我是喜歡放部電腦在自己心口上面用. 但總是害怕接收到的wifi會通過部電腦把輻射傳遞到我身體裡, 導致健康問題. 跟iPhone放在褲袋裡殺精一樣, 這恐guey存在於腦海裡一個隱藏的地方, 跟一si si的罪惡感bong埋一起.
所以當大量不知道是否可信的新聞開始講新的5G網絡有機會危害你健康時我馬上到google 做資料收集. 我找的是... 大家好又是我暗網仔...等等返反房間先
一起去看大家對5G一些誤解和一些真相.


1豬. 煤氣燈

歷史上: 人類對新科技感到懷疑已經不是第一次. 18世紀: 英國, 意大利等歐美國家開始商業生產街上放置煤氣燈. 即使這個決定令到當時犯罪luet大dit, 1831年天主教教宗Pope Gregory 16是禁止煤氣燈的使用. 說上帝是有計劃地設立定日出日落的時間, 在晚上有光是wuy fan上帝的法則. 除此之外亦有可能破wai人sik bit早午晚的生理時鐘.

2豬. 電話線
18世紀末美國Bell電話公司成功證明電話線的效率後開始在多個中上階層社區建立這些高大又被yu為醜陋的建築物. 當時有多位有錢人也反對自己社區起電話線choo. 直到1916年Texas州一位黑lo Jesse washington因被懷疑姦殺自己女主人被jit mo, 閹割, 燒死然後掛在choo上. 最恐怖是之後有錢的白人是jan成電話線choo的建置, 因為可以同樣地choo fut其他黑lo. 因為這段歷史, 這些建築物就存在到現今.

3豬. 我想關於5G陰謀論(show title)最大的標題是有關現在的病毒.今年1月22號比利時報紙 ‘Het Laatste Nieuws’ 醫生Kris Van Kerckhoven指出自2019年武漢建立了多個5G信號塔. 雖然該報導好快被下架, 但已足夠在網上燃點一埸大的反5G爭論. 產生上街抗議事件和網上多個陰謀論. 最後多個信號塔也真實地被燃點了. 有陰謀論是信號塔會發出beng dook. 甚至被指英國銀紙上有出現來影響大jung的5G信號塔圖像. 塔上面亦有yi似一lup beng dook的東西.

雖然我之前講過多個陰謀論,但講到明是 ‘病毒’ 影響人而不是 ‘細菌. 一件物件上的細菌不足夠使你有這個病.

直至我網上看到最後5G輻射會削弱你免疫系統的陰謀論. 這觸發到我之前對自己生活習慣那個恐懼. 我也會問: 點解要5G?

4豬. 電訊科技 (show title) 自1979年日本Nippon telegraph and telephone推出了1G(1 generation) 後已經改變了我們人和電線的關係. 除了唔洗kik親是重點外, 這是手機文化的開始.
網絡能在區域而‘cells’ 的分bo, 每區被一個goo定收發器控制.
所有ging ying 1G,2G,3G,4G,5G的電訊公司都是以Network standards去設計產品. Bandwidth, technology 全部一ji. 在意bps (bits per Second) ‘每秒’ 計算的速度. 1G是2.4kbps, 到1991年芬蘭推出而digital傳輸更可靠的2G是64kbps, 3G終於可以已2mbps luw lam網站, email, 看照片和影片和用智能手機. 4G高達1Gbps是 ‘3高’ high speed high quality 和high capacity,而5G是能夠高dat 4G的10倍10Gbps. 你現在電話速度的10倍.

5豬. 在危險(show title) 層面上這麼kwah jeung的科技會否大量影響我們認知的現實? 是會影響的. 兩大元soh是: EMF和RFR.

EMF (electromagnetic field)是電磁輻射會影響到的面jik. 即是信號tap既整個fan wuy.
而能影響人體的RFR(radiofrequency radiation) 是我們整個5G debate要集中的那一個點.
其實我們很多日常生活的東西也有這種RFR. 太陽, 你電話mon, mei bo low, x-ray多多少少全部都有.
但這種影響是否危險基於那種RFR有沒有一樣叫游離這樣東西. 簡單一點, 沒有游離的RFR, 列如電話sin, FM電台, WiFi 根本不夠強去影響我們的化學鍵. 跟有游離的核武不同.
5G本身也是一種沒有游離的RFR, 所以基本上不會對我們人類有破壞性.
但因為5G所用的24至90 gigahertz頻率比之前電訊科技用多很多倍, 理論上應該影響我們的身體更大. 但這方面實質的科學數據或實際會做到什麼就比較難找到.

跟guey現有data不能夠説5G未來會傷我們. 坦白一些快一點的服務誰不想用啊? 我本人覺得不要因為一點末jing sut的事jo ouy自行得更遠.
當年Pope Gregory 16不想人用煤氣燈不是因為他關心人民, 是因為他怕新科技會令他失去koon lik.

5G信號塔會否危害你健康嗎?
5G網絡會否危害你健康嗎?
[警告!!!] 5G網絡會否危害你健康?
