26. Safety in Work with Radiation

Occupational safety is an extremely important area that aims to protect the physical integrity of workers. One of the most delicate areas is that involving work with radiation. Radiation is electromagnetic waves or particles that propagate with a certain amount of energy. They can be ionizing or non-ionizing and, if not properly controlled, can cause serious harm to workers' health.

Ionizing radiation is radiation that has enough energy to ionize atoms or molecules, that is, it is capable of removing electrons from an atom or molecule, making them ions. Ionizing radiation includes X-rays, gamma rays, alpha and beta particles, and neutrons. Exposure to these radiations can damage the DNA of cells, which can lead to mutations and, in extreme cases, cancer.

Non-ionizing radiation, on the other hand, does not have enough energy to ionize atoms or molecules, but it can cause excitation. This means that it can increase the energy of atoms or molecules, but not enough to ionize them. Non-ionizing radiation includes ultraviolet radiation, visible light, infrared radiation, microwaves and radio waves. Exposure to these radiations can cause burns, damage to the eyes and, in some cases, can increase the risk of skin cancer.

It is therefore critical that workers dealing with radiation are properly trained and aware of the risks involved. They should know how to properly use personal protective equipment (PPE), such as lead gloves, lead aprons, goggles, and dosimeters, which are devices that measure the amount of radiation a person has been exposed to.

In addition, it is essential that workplaces where radiation work is carried out are properly designed and maintain strict radiation control. This includes the use of lead or concrete shields to block radiation, adequate ventilation to prevent radiation buildup, and adequate signage to alert workers to the presence of radiation.

Workers should also be monitored regularly to see if they have been exposed to unacceptable levels of radiation. This can be done through regular medical examinations and the use of dosimeters. If excessive exposure to radiation is detected, the worker must be removed from the work environment and receive appropriate medical treatment.

In summary, safety in radiation work is an issue of utmost importance that requires a careful and systematic approach. It is essential that workers are properly trained, that the work environment is properly designed and controlled, and that regular monitoring is carried out to ensure the health and safety of workers.

This e-book course on workplace safety aims to provide you with in-depth knowledge of all these aspects, so that you can ensure a safe and healthy work environment for everyone. Workplace safety is not only a legal obligation, but also a matter of social and ethical responsibility. Therefore, we invite you to join us on this learning journey and become a competent and aware workplace safety professional.
