Wireless access points are also often close to humans, but the drop off in power over distance is fast, following the [[inverse-square law]].<ref name="Foster2007">{{Cite journal|last= Foster|first= Kenneth R|title= Radiofrequency exposure from wireless LANs utilizing Wi-Fi technology|date=March 2007|journal= Health Physics|volume= 92|issue= 3|pages= 280–289|doi= 10.1097/01.HP.0000248117.74843.34|pmid= 17293700|bibcode= 2007HeaPh..92..280F|s2cid= 22839684}}</ref>
The position of the [[United Kingdom]]'s [[Health Protection Agency]] (HPA) is that “...radio frequency (RF) exposures from WiFi are likely to be lower than those from mobile phones". It also saw “...no reason why schools and others should not use WiFi equipment".<ref name="HPAWiFi">{{Cite web|url= http://www.hpa.org.uk/HPA/Topics/Radiation/UnderstandingRadiation/1199451940308/|title= WiFi|access-date= 27 December 2009|date= 26 October 2009|publisher= [[Health Protection Agency]]|archive-date= 24 December 2009|archive-url= https://web.archive.org/web/20091224051807/http://www.hpa.org.uk/HPA/Topics/Radiation/UnderstandingRadiation/1199451940308/|url-status= dead}}</ref> In October 2007, the HPA launched a new "systematic" study into the effects of WiFi networks on behalf of the UK government, in order to calm fears that had appeared in the media in a recent period up to that time".<ref name="HPAWiFiStudy">{{Cite web|url= http://www.hpa.org.uk/webw/HPAweb%26HPAwebStandard/HPAweb_C/1195733726123?p=1171991026241|title= Health Protection Agency announces further research into use of WiFi|access-date= 28 August 2008|publisher= [[Health Protection Agency]]|archive-date= 17 June 2008|archive-url= https://web.archive.org/web/20080617172507/http://www.hpa.org.uk/webw/HPAweb%26HPAwebStandard/HPAweb_C/1195733726123?p=1171991026241|url-status= dead}}</ref> Dr Michael Clark, of the HPA, says published research on mobile phones and [[radio masts and towers|masts]] does not add up to an indictment of WiFi.<ref>{{Cite news| first= Nicki| last= Daniels| title=Wi-fi: should we be worried? | date= 11 December 2006| url =http://www.timesonline.co.uk/tol/life_and_style/health/features/article665419.ece | archive-url =https://web.archive.org/web/20070226192218/http://www.timesonline.co.uk/tol/life_and_style/health/features/article665419.ece | url-status =dead | archive-date =26 February 2007 |work=The Times | access-date = 16 September 2007 | quote = All the expert reviews done here and abroad indicate that there is unlikely to be a health risk from wireless networks. … When we have conducted measurements in schools, typical exposures from WiFi are around 20 millionths of the international guideline levels of exposure to radiation. As a comparison, a child on a mobile phone receives up to 50 percent of guideline levels. So a year sitting in a classroom near a wireless network is roughly equivalent to 20 minutes on a mobile. If WiFi should be taken out of schools, then the mobile phone network should be shut down, too—and FM radio and TV, as the strength of their signals is similar to that from WiFi in classrooms.... | location=London}}</ref>
