Radiation Detector,radiation meter

General knowledge of electromagnetic radiation:

All electrical devices send out radiation more or less. Radiation overdoses will do harm to the human body in many ways,such as the following ones:

. thermal effects: the human body contains over 70% water. When the water molecules are radiated by electromagnetic waves,they will frictionate mutually,causing the organs to heat up and influencing their normal work.

.Non-thermal effects: The organs and tissues in the human body have weak electromagnetic fields,which are stable and in order. Once disturbed by outside electromagnetic fields,their balance will be damaged and thus the human body will be impaired.

.Cumulative effects: After thermal and  non-thermal effects impact on the human body,the body will start ot recover to normal by self-healing. But if it is radiated again by electromagnetic waves before it recovers,the harm will be accumulated. Over time,it will be permanent morbidity and threaten human life. As to people who are always radiated by electromagnetic waves,even if the power and frequency are low,there may be unexpected lesions,thus it should be taken closed attention to.

Some people tend to walk around while they are on the phone.But they hardly realize that frequent moves will cause the signal strength to fluctuate,reusulting in short-term high transmission power.Besides,if you make phone calls in a moving car,in order to avoid frequent area shifts,the phone will designate a high-power base station with a wider coverage for service supply,and the phones transmission power will increase because of the larger transmission distance.

Special elucidation:

The above-mentioned tips are only for your reference,and all the harms above potential ones which are possible to occur.The actual harm is closely related to both the quality of electrical devices and the circuit condition of the environment.We suggest that people should judge by referring to the best result of the radiation detector.

Specifications:

Test range:> 50μw/c

Output: 1.5V(AAA)×2

Dimensions: 148×20×25mm

Weight: approx. 40g(battery included)

Applicable scope:

This pen can be used to test:

.The radiation hazard radius of three-phase plug electrical devices with a defective loop circuit while in use

.The radiation hazard radius of all all two-phase plug electrical devices

.The radiation hazard of high voltage transmission line towers

.The radition hazard radius of GSM mobile phones

.Unusual electromagnetic radiation fluctuations in other environment

.Also can be used as a primary test tool for kinds of protection articles against electromagnetic radiation.

A Common Method for testing mobile phone radiation:

First,hold a mobile phone in hand at its bottom part,not more than two-thirds of its length.Then,put the detector close to the phones receiver.At last,dial a number and make a call,and if the radiation is beyond the safety level the detector will flicker red and beep.Otherwise,it remains silent.

Attentions:

Replace the battery in a timely manner,so as to avoid battery aging,which could cause liquid leakage and damage to the pens ciurcuit board.When this high sensitivity electromagneti radiation detector warns with a much weaker beep,you need to pull out the red cap on the bottom and replace the battery in accordance with the indication on one side of the detector.

Notes:

This high sensitivity electromagnetic radiation detector is developed with an imported high sensitivity sensor and precise circuits.When it detects radiation overdose,it will flicker red and warn with continuous beep,and it will not stop unless the radiation at the place where you are decreases to a safe level.

This radiation detector is convenient to use,responses promptly and works low power consumption.It has many advantages which include that with battery being loaded,it can detect the radiation in the environment at all times.

Warn prompt:

.As for a three-phase plug with a good loop circuit,its electromagnetic radiation can be exported through the loop without a hitch,thus the test result will be no beeping.If it beeps when you test the three-phase plug,it means that there is a bad loop circuit causing the radiation ot be trapped.If you often use this kind of electrical appliance,you should try to keep yourself in a place that detector will not beep.For a two-phase plug,as it has no ground loop,usually there will be radiation,thus detector will beep.

By adopting the gap pulse working principle,GSM cell phones work with stable signals,but their radiation level is comparatively high.Moreover,when the signal is weak,the radiation during a call could be 1000 times more than that when the signal is not good.As for CDMA phones which adopt the directional antenna system,their design is integrated with an environmental-protection concept,so the test result with this detector should be silent with no beeping.

While testing a computer mainframe,a keyboard or a monitor that people often contact directly,a reasonable result should be the detector is silent without beeping.If it flickers red and beeps,you should immediately use certain equipment to eliminate the computers radiation.
