Understanding the origin and types of radiation

What is radiation?

We often hear about radiation, but what is it exactly? Simply put, radiation is a form of energy in motion. It can take the form of waves or particles and is constantly around us.

Origin of radiation

Radiation comes from a variety of sources, both natural and artificial. We are all exposed to some level of radiation on a daily basis from these different sources.
1. The natural springs radiation include, among others, cosmic radiation from space, radioactive minerals present in the ground and internal radiation in our body.
2. The artificial sources of work and leisure radiation, in specialized tools and equipment. Notable examples include x-rays, scanners, nuclear power, and atomic bombings.

Types of radiation

There are many types of radiation, which can be classified into two main categories: ionizing and non-ionizing radiation.

Ionizing radiation

Ionizing radiation has enough energy to strip electrons from atoms, which can damage cells and DNA. The most common types of ionizing radiation include:
1. Alpha rays : They are produced by the radioactive decay of heavy atoms. They don’t penetrate very far and can be blocked with a simple sheet of paper or human skin.
2. Beta Rays : More penetrating than alpha rays, they are made up of negatively charged particles.
3. Gamma rays : They are extremely penetrating and can penetrate several centimeters of lead.

Non-ionizing radiation

Non-ionizing radiation has less energy than ionizing radiation and is not capable of ionizing atoms. Types of non-ionizing radiation include:
1. Radio waves and microwaves : These low frequency waves are used in mobile phones, microwave ovens, etc.
2. Infrared waves : These waves are produced by heat and are used in remote controls and thermal cameras.
3. Light waves : Visible to the human eye, this is what allows us to see colors.
4. Ultraviolet waves : Although less energetic than X-rays, they can still cause DNA damage and cause skin cancer.
So even though we can’t see or feel radiation, it’s important to remain aware of its presence and understand how it works. This allows us to take the necessary measures to protect ourselves and our environment. Even more so now that technology and modern industry continue to increase our exposure to these different forms of radiation.

Identify and quantify radiation exposure

What is radiation exposure?

Radiation exposure refers to the amount of ionizing radiation absorbed by a living organism. It can be caused by a variety of sources, including medical devices, radioactive materials, naturally occurring substances in the environment, and nuclear energy-related accidents.

Identifying Radiation Exposure

There are several ways to identify radiation exposure, and the method chosen will depend on both the suspected radiation source and the specific situation of the individual involved.
One way to detect radiation exposure is to use a dosimeter. These devices, like the Radex dosimeter where the Gamma-Scout dosimeter, are capable of detecting the presence of ionizing radiation and quantifying the level of exposure.
Another method is to do blood tests. Indeed, high exposure to radiation can lead to a drop in the number of white blood cells, an anomaly easily detectable by a simple blood test.

Quantifying radiation exposure

Once identified, radiation exposure can be quantified to enable better risk management. The most commonly used units of measurement to quantify radiation exposure are Grays (Gy) for absorbed dose, Sieverts (Sv) for equivalent dose, and Bequerels (Bq) for radioactive activity.
To accurately measure the level of radiation exposure, it is necessary to use an appropriate measuring instrument. Dosimeters, mentioned previously, are commonly used for this purpose. But other devices, such as Geiger-Müller counters, can also be used.

Protect against radiation exposure

There are many ways to protect yourself from radiation exposure, including:

  • use custom protective equipment, such as radiation protective clothing and eyewear, available from brands like LeadX Or RadSafe;
  • work remotely or use shields or shields to reduce exposure;
  • limit the time spent near sources of radiation;
  • schedule regular medical examinations to monitor for signs of radiation exposure.

By understanding how to identify and quantify radiation exposure, and taking necessary precautions to limit it, we can all help prevent radiation risks.

Techniques and equipment to protect against radiation

Protecting yourself against radiation: a necessity for everyone

Whether you are a worker in a nuclear power plant, a laboratory researcher, or a simple citizen wishing to protect yourself against a possible natural or technological disaster, we are all potentially affected by exposure to radiation. This guide aims to enlighten you on the existing techniques and equipment to protect you against the potentially harmful effects of radiation.
First thing to know: not all radiation equipment is 100% effective. Their main task is to minimize the danger as much as possible. Here are some methods, techniques and equipment that can help you.

Understanding radiation

Radiation are waves or particles emitted by unstable atoms. There are two types of radiation: ionizing (like X-rays or gamma rays) and non-ionizing (like radio frequency waves). Radiation can damage living tissues, causing the development of diseases such as cancer or acute radiation syndrome.

Limit your exposure

The golden rule to protect yourself from radiation is to limit your exposure. This can be accomplished using the following:

  • Distance: the further you are from the radiation source, the less you are exposed to it.
  • Time: the less time you are exposed to a source of radiation, the less irradiated you will be.
  • Shielding: Proper shielding can prevent radiation from reaching you.

Personal protective equipment

There are a variety of radiation protection equipment available. Here are some common examples:

  • Protective suits RadSafe : offer complete protection, but are generally reserved for radiation protection professionals.
  • Lead jackets and aprons: This protective gear is typically used by healthcare workers who are exposed to radiation regularly, such as x-ray technicians.

Radiation detection systems

Detecting radiation levels is crucial to ensure exposure remains within safe limits. Here are two types of detectors you might consider:

  • The Personal Irradiation Indicator (PIP): These are small devices that you can carry with you to measure radiation doses.
  • The Geiger counter LND : It is essential to assess the presence of radiation in a given area.

Nutrition as a shield

Certain vitamins and minerals can help protect the body from the effects of radiation. These include:

  • Iodized potassium: It is recommended in case of exposure to radioactive iodine. It protects the thyroid by flooding it with safe iodine, preventing radioactive iodine from being absorbed.
  • Vitamin B9 (folic acid): It helps produce and maintain new cells, which is crucial after exposure to radiation.

Remember, none of these solutions is an absolute guarantee against all types and levels of radiation. However, by combining these precautionary techniques and tools, you will maximize your chances of staying safe even if exposed.
