Abstract
The invention discloses an electromagnetic wave measuring method. The electromagnetic wave measuring method is achieved through the following steps of (1) immersing two same metal bodies into a nonmetal container containing water with the electrical conductivity being from 100 to 1000 micro siemens per centimeter; (2) respectively connecting the two metal bodies through two leads and enabling the leads to extend and expose out of the water surface; (3) connecting a resistor, a voltage meter which is in parallel connection with the resistor and two leads to form into a loop with the two metal bodies serving as two electrodes; shielding one metal body through a shielding box under the condition of having an electromagnetic wave radiation source, wherein voltage can be read from the voltage meter and a voltage numerical value and the electromagnetic radiation intensity of the unshielded metal body are in a direct proportion. According to the electromagnetic wave measuring method, the resistor forms into the loop and accordingly tiny currents are amplified to be measurable voltage with a large value, the intensity of electromagnetic waves radiating to the metal surfaces can be known by measuring the voltage value, and an electromagnetic radiation measuring sensor which is low in cost, simple and accurate in measuring is provided.
Description
Technical field
The present invention relates to a kind of measuring method of electromagenetic wave radiation amount, is ordinary surveying electromagenetic wave radiation amount technical field.
Background technology
Take mobile phone as utilize the various electric equipments of radiowave the to become mark that we are different from other epoch these epoch of representative.The thing followed be people on the worry of electromagnetic radiation on the impact of health: around me, have how many radiation on earth? traditional survey sensor complex structure, making requires high, so expensive.As Chinese patent CN102375096A and CN102375094A, all disclose a kind of electromagnetic radiation measuring device, its structure and principle are extremely complicated, there is requirement for the frequency measuring electromagnetic radiation simultaneously, measure after needing to be amplified electromagnetic wave by high-frequency signal amplifier, be applicable to industrial products.For another Chinese patent CN102346220, have employed three grades of electric capacity and amplify electromagnetic wave, measuring result error is very large, and circuit structure is complicated.Chinese patent CN102967773A, its structure is simple, the measurement of applicable daily life especially household electrical appliance electromagnetic radiation, but does not disclose its ultimate principle.
So low cost, simple electromagenetic wave radiation sensor are the exploitation objects of current technology.
Summary of the invention
The invention provides a kind of measuring method of electromagenetic wave radiation amount, measure structure extremely simple, judge electromagnetic radiation intensity simultaneously according to current value, save cost, versatility is extensive, measures electromagnetic wavelength unrestricted.
The present invention is realized by following technical scheme:
A measuring method for electromagenetic wave radiation amount is realized by following step:
(1) two pieces of same metal bodies are immersed in hold conductivity be in the nonmetallic vessel of the water of 100-1000 μ S/cm;
