Radiation is a form of energy that comes from a source and travels through a medium, including vacuum. Sun rays are one of the most familiar forms of radiation. Light heat and sound, all are types of radiation. But the radiations we need worry about are called ionizing radiation. It can cause damage to matter, particularly living tissues by changing the structure and even the DNA. Obviously, at high levels of exposure, it is extremely dangerous to you and even your children who are not born yet!
Unstable atoms are radioactive. In order to reach a stable configuration they emit energy or mass or both. The different types of ionizing radiations are:. These are helium nuclei consisting of two protons and two neutrons. They are emitted from naturally-occurring heavy elements such as uranium and radium, and from some man-made elements.
They are very powerful but cannot penetrate the skin. These are fast-moving electrons emitted by radioactive elements. They penetrate the skin but can be easily shielded by using few millimeters of wood or aluminum. Beta-radioactive substances are also safe if kept in appropriate sealed containers. These are high-energy electromagnetic waves, emitted in many radioactive decays and are highly penetrating. Gamma rays are the main hazard to people.
All of us receive about 0. Virtually identical to gamma rays, X-rays are ionizing electromagnetic waves. They are not nuclear in origin. They are produced artificially and on demand rather by inexorable physical processes. High exposure to X-rays is extremely dangerous because of its high energy and ionizing capacity. They are very high-energy particles, mostly protons which bombard the earth from outer space.
They comprise about one-tenth of natural background exposure at sea level, and more at high altitudes. Uncharged particles mostly released by nuclear fission the splitting of atoms in a nuclear reactor.
They are not normally a problem outside nuclear plants but fast neutrons are very destructive to human tissue. They can even make other, non-radioactive materials, become radioactive.
The main ill-effects of radiation arise from fear and not the radiation itself. The health effects of exposure both to radiation and to chemical cancer-inducing agents or toxins must be considered in relation to time. Though the exposure can be life threatening but low level of radiation absorption does not pose any major threat to humans:.
In most countries the current maximum permissible dose to radiation workers is 20 mSv per year averaged over five years, with a maximum of 50 mSv in any one year. Though low-level exposure to radiation is not life threatening but you need to make sure that the exposure is indeed safe.
People receive some small doses of radiation from natural sources every day which do not harm our bodies. But when the radiation level increases due to some causes, it becomes dangerous as it can change the state of atoms of our cells. Nowadays a lot of places are contaminated with radionuclides due to human activities. Check the ratio of background radiations:. You need an equipment to check the level of radiation in surroundings and shield you from its ill-effects.
There are plenty of radiation detectors easily available in the market but not all of them are suitable for your household usage. Some specific radiation detectors can only shield you from certain radiations and not provide an all round safety for you and your surroundings.
A compact dosimeter for household is highly recommended.Updated November 20, by Vann Vicente. This wiki has been updated 20 times since it was first published in February of For those who are worried about the effects of electromagnetic frequencies being emitted by all the devices in our lives these days, you can now measure them with one of these EMF meters.

And yes, the Alternative Tech International Ghost Meter may still be a good choice for your paranormal adventures, though we question its capabilities with regards to more practical tasks.
Once thought to be separate forces, electricity and magnetism have since been joined into a unified theory called electromagnetism. The study of electromagnetism deals with how electrically charged particles interact with each other and with magnetic fields.
Electromagnetic radiation takes many forms. Common examples include radio waves, microwaves, X-rays and gamma rays. Sunlight is also a form of electromagnetic energy, but the visible light it gives off is only a very small portion of the electromagnetic spectrum, which contains a broad range of wavelengths.
Many things in daily life also create electromagnetic fields. Electronics such as cellular phones, video game consoles, computers, radios, and even simple power outlets give off electromagnetic fields.
Larger fields are created by larger sources of electricity. Power lines, refrigerators, and generators give off a larger field than a small clock radio, for instance. Electromagnetic fields also exist in nature, such as when the atmosphere becomes charged during a lightning storm. The job of an EMF detector is to pick up signs of these electromagnetic fields. Stronger currents give off stronger EMF readings. The problem with electromagnetic fields is that they are rarely, if ever, visible to the naked eye, though they are often present in the atmosphere from natural electrical or magnetic sources.
This is why EMF detectors are so important. EMF detectors indicate the presence of electromagnetic frequency through the use of one or more receiving antennae that measure differing AC or DC electrical currents.The esi 24 EMF detector - now with sound demodulation.

Unfortunately most meters in the market do not include one or all of the above basic features. All these above factors are analyzed in our high frequency meter, low frequency meter and radioactivity meter guides.
Please read them carefully before you purchase! High frequency meters should be able to record radiation in the frequency range MHz at least which most modern wireless radiation sources emit. Some have an antenna attached that can help you locate the direction fo the radiation, others produce different sounds according to the radiation source, others have both features. Learn more about high frequency radiation meters, sources and safety limits.
All wired radiation sources connected to the power network generate electrical alternative current AC fields due to electrical voltage.
When electrical current flows through the conductors when there is electricity consumption AC magnetic fields are also produced. Low frequency meters should be able to record radiation in the frequency range Hz at least which is the main frequencies of electrical grids. Measuring magnetic fields is, in our opinion, the most important measurment you should take before buying or renting property, because high magnetic fields are difficult and expensive to reduce.Free shipping.
