Abstract

PURPOSE:To emit an alarm before the quantity of electromagnetic waves reaches dangerous quantity by always measuring the exposure quantity of electromagnetic waves of a person living in a place where invisible electromagnetic waves fly about. CONSTITUTION:The electromagnetic waves taken in through a wide-band antenna 1 are amplified in a predetermined gain by an ultra-wide-band amplifying circuit 2 and rectified by a rectifying circuit 3 to extract a DC component. This DC component is converted to a digital signal by an A/D converter 4 and said signal is multiplied by a time by an integration circuit 5 to integrate the level of the signal and the integration result is compared with a reference value 7 by a comparison circuit 6. When the integration result reaches the reference value by this comparison, an alarm is generated by a notice part 8. Therefore, by always carrying the electromagnetic wave measuring device thus constituted, an alarm is emitted to a person engaging in a broadcasting station, a radio station or a microwave relay station based on the exposure quantity of electromagnetic waves before adverse effect is exerted on a human body.

[Industrial Application Field] The present invention relates to a method for measuring electromagnetic waves that issues a warning when a certain value is exceeded by measuring and integrating the amount of electromagnetic waves that would have an adverse effect on the human body, etc. Regarding equipment.

2. Description of the Related Art Generally, radiation refers to high-energy alpha rays, beta rays, and gamma rays, and is thought of as ionizing radiation that causes ionization when it hits a substance. However, in addition to these types of radiation, there are also various types of radiation around us, such as lower-energy light, radio waves, and magnetic fields.

A typical example of devices that utilize such electromagnetic waves is a microwave oven that can heat things that are common in ordinary households. This microwave oven applies the principle that when an object receives high frequency waves (electromagnetic waves), its molecular motion increases, and this motion turns into heat. In the field of clinical medicine, there is also thermotherapy, which treats affected areas by irradiating them with weak electromagnetic waves. In addition, it is not limited to these, but there are countless industrial, business, home appliance, and
A large amount of general equipment or equipment for toys etc. is produced.

[0004] As described above, it has been believed that electromagnetic waves do not cause any harm to the human body, etc., and this principle has been used to apply them in various fields. It is applied not only to microwave ovens, but also to radio waves (electromagnetic waves) from broadcasting stations, high-frequency furnaces, simple radios, mobile phones, cordless phones, and many other things.

[0005]

[Problems to be Solved by the Invention] However, recently, there have been some documents claiming that electromagnetic waves have an effect, and the problem of the negative effects of electromagnetic waves on the human body is drawing attention. In other words, when exposed to ionizing waves, ions and peroxides are generated within cells, damaging genes. This gene is involved in the control of cell differentiation and proliferation, and is thought to be linked to cancer. Furthermore, in the case of ionizing waves, there is no minimum threshold for inducing cancer. For this reason, it is considered that carcinogenic effects accumulate in proportion to the amount of radiation exposure. This is because advances in science and medicine have led to questions about their safety.

[0006] As a specific example, for example, there have been burns and fatal accidents caused by high frequency (electromagnetic waves) from disparate antennas at radar bases. Furthermore, as mentioned above, since microwave ovens used in general homes can heat things, the temperature of the human body, etc. will rise when exposed to electromagnetic waves. For example, according to a recent medical book on how electromagnetic waves affect the brain of the human body, human cells are
It has been proven that even good cells die when the temperature exceeds C. This property is used to treat cancer and the like. Furthermore, at close range to the source of electromagnetic waves,
Even with a low-power device, the electric field strength can be extremely high, which naturally raises the temperature of people in close proximity.

[0007] As described above, while electromagnetic waves are useful in applications such as everyday electrical appliances and in the treatment of cancer, etc.,
It has an adverse effect on the human body. A simple way to prevent these electromagnetic waves is to shield the source of the electromagnetic waves, or shield people from the electromagnetic waves. However, since most electromagnetic waves are used for communications,
It's easy to shield, but you can't. However, if it is possible to measure the amount of electromagnetic waves, it is possible to determine the safe zone, which gives peace of mind.

[0008] In the past, there have been devices that measure electromagnetic waves or analyze electromagnetic waves, as well as electric field strength meters that measure the intensity of electromagnetic waves. They merely measure the electric field strength at a certain frequency or only a part of a frequency band, and neither of these measures is intended to warn of adverse effects on human bodies going about their daily lives. In other words, since humans are constantly moving, they are not exposed to a fixed amount of electromagnetic waves, but the cumulative amount is the problem, and something is needed that can remeasure the cumulative amount and issue a warning. .

[0009] The present invention was developed in response to these circumstances, and is a method of constantly measuring the amount of electromagnetic waves that humans and others who live in the presence of invisible electromagnetic waves are exposed to. An object of the present invention is to provide a method for measuring electromagnetic waves and a measuring device for the same, which can issue a warning before a dangerous amount is reached.
