Amateur Radio RF Safety Calculator


Calculation Results

 

Average Power at the Antenna 1 watts
Antenna Gain in dBi 6 dBi
Distance to the Area of Interest 5 feet
1.524 metres
Frequency of Operation 2400 MHz
Are Ground Reflections Calculated? Yes
Estimated RF Power Density 0.035 mW/cm2
  Controlled
Environment
Uncontrolled
Environment
Maximum Permissible Exposure (MPE)
5.005 mW/cm2
1.005 mW/cm2
Distance to Compliance From Centre of Antenna
0.4678 feet
0.1426 metres
0.9843 feet
0.3 metres
Does the Area of Interest Appear to be in Compliance?
yes
yes

 

 
Interpretation of Results
  1. The power value entered into these calculations should be the average power seen at the antenna and not Peak Envelope Power (PEP). You should also consider feedline loss in calculating your average power at the antenna.

  2. If you wish to estimate the power density at a point below the main lobe of a directional antenna, and if the antenna's vertical pattern is known, recalculate using the antenna's gain in the relevant direction.

  3. Please also consult FCC OET Bulletin 65 Supplement B, the Amateur Radio supplement to FCC OET Bulletin 65. It contains a thorough discussion of the RF Safety regulations as they apply to amateur stations and contains numerous charts, tables, worksheets and other data to help determine station compliance.

太好了!大侠总能找到正确答案啊。

手机不好算,因为是近场 - 大概离开8厘米就安全了

可贴着耳朵不到8厘米啊?

什么叫安全。0.31m就安全,0.29m就不安全?微波和wifi效果一样吗?60hz引起癌症的机理还没搞清呢

60Hz引起癌症?好像一例都没有吧?你又在引用被否定的东西了!

WiFi的辐射是一种微波。你的问题怪怪的。。。

微波炉内的微波是2.45GHz,与WiFi的很接近,但功率就大太多了

老T, 你的calculator是为amateur radio做的,cell phone用SAR

在太阳下做日光浴的辐射会比手机贴在脸大的多
