Are you interesting in improving your HAZMAT knowledge?

This software is very interesting to train or improve your knowledge in hazardous materials emergencies, furthermore we will contribute to increase industrial safety.

The main target of this software is to improve your knowledge in road hazardous material accidents, and  moreover you will be able to prove your skills in all kind of accidents.

I recommend it for emergency teams as a training, because it is very important to keep your knowledge up in this kind of situations, it could save lives.

You can download the spanish versión here:

To get other language version you have to contact aself.

In this video you can see a Demo of HazMat 4.0.

Nuclear #3, Radiologic Risk.

Nowadays, it is common to find NRBQ (Nuclear, Radiologic, Biologic, Chemical) teams among emergency services.

To achieve success it is very important to train a lot and to have a deep knowledge of this kind of risks.

Today, in this post, I am going to talk about radiologic risk and its Spanish legislation, which is written by the Nuclear Authority in Spain (Consejo de Seguridad Nuclear).


Emergency groups

The first point to consider it is how to identify the teams which are going to manage the emergency. The NRBQ emergency teams are not going to do recuperation works, their target is the security of the citizens and save their lives (in Spain).

We can find the max level of exposition for the emergency teams  in the RD 1564/2010. Moreover CSN (Nuclear Security Board) advertised a technic guide to inform how to apply that legislation.

Group 1

Urgent actions in the accident place.

(Save lives, prevent serious injury or prevent a worsening of the accident that could result insignificant doses to the public)

The director of the emergency, through the radiological group, makes every effort to keep the dose levels of the staff below the level of occurrence of severe deterministic health effects included in Annex Table VI.5 VI.

International recommendations by the CSN  recommended to the Spanish Regions a max value of  dose for this group in 500 mSv. Exceptionally, and to save human lives may exceed these values.

The people who will do these jobs could receive higher dose limits for exposed workers laid down in RPSRI * so  they must be informed, trained and volunteers and it should be excluded pregnant women.

However, Table 5.5 of the CSN technical guide collects quantitative radiological criteria for implementing protective measures taken from the International Basic Safety Standars (BSS) of the IAEA (International Atomic Energy) established as a measure of protect medical advice before a new exposure or if the employee so requests in dose limit of 200 mSv.

Group 2

Emergency protection measures and other actions to protect the population.

The emergency director through radiologic group will do all efforts to reduce the dose to the staff during the emergency below max annual dose limit for the exposure in one year requirement  in 50 mSv effective dose by RPSRI.

It has to be taken into account when setting the dosimeters of the staff who will intervene in the emergency.

Emergency zones and intervention development

Very similar to the zones of hazardous material intervention but with different nomenclature and taking into account that the end of one and the beginning of the next is determined by the dose rate.

Urgent measures zone

It is the interior of the bounded zone, in which it is necessary to take certain protective measures to prevent the emergency teams of receiving higher doses than laid down in DBRR for staff intervention group 2 and to prevent the population receive higher doses than the doses established in the intervention levels for urgent protective measures. This area will include the zone where the exposure level exceed 5 mSv / h.

Alert zone

It is the zone in which it is necessary to take protective measures to prevent the population receives doses higher than emergency teams. This area will include the zone where the exposure is expected to exceed 100 mSv / h.

Free zone

Outside the warning area, which is not necessary to apply protective measures because the doses are lower than those established intervention levels . The next figure show the definition of the areas of planning, showing the arrangement of zones and zone criteria apply in both cases.

In the first moments of an emergency you may not have the means to determine the level of exposure around the stage in which it has occurred. In these cases the DBRR provides the following criteria to determine the scope and dimensions of the zones, in open spaces and indoors.
In open spaces:

  • Urgent measures zone will be the circle whose centre is the focus of risk and whose radius is 100 mts.
  • Alert zone is the annulus whose centre is the source of risk and whose inner radius is 100 mts and 200 mts outside.
  • Free zone is outside the Alert Zone.

Nuclear #1, Gestión de emergencias radiológicas

En este artículo voy a compartir documentación relativa al curso de «Gestión de emergencias radiológicas» realizado en la Escuela Nacional de Protección Civil e impartido por el Consejo de Seguridad Nuclear.

Este creo que es un tema muy interesante a tener en cuenta ya que muchas veces, es más el miedo debido al desconocimiento lo que nos bloquea y no nos deja actuar correctamente.

¿Qué es la radiación?

El fenómeno de la radiación consiste en la propagación de energía en forma de ondas electromagnéticas o partículas subatómicas a través del vacío o de un medio material.

La radiación propagada en forma de ondas electromagnéticas (rayos UVrayos gammarayos X, etc.) se llama radiación electromagnética, mientras que la radiación corpuscular es la radiación transmitida en forma de partículas subatómicas (partículas α, neutrones, etc.) que se mueven a gran velocidad en un medio o el vacío, con apreciable transporte de energía.

Si la radiación transporta energía suficiente como para provocar ionización en el medio que atraviesa, se dice que es una radiación ionizante. En caso contrario se habla de radiación no ionizante. El carácter ionizante o no ionizante de la radiación es independiente de su naturaleza corpuscular u ondulatoria.

Son radiaciones ionizantes los rayos X, rayos γ, partículas α y parte del espectro de la radiación UV entre otros. Por otro lado, radiaciones como los rayos UV y las ondas de radio, TV o de telefonía móvil, son algunos ejemplos de radiaciones no ionizantes.

En el siguiente documento os dejo las presentaciones del curso de «Gestión de riesgos radiológicos», espero que sean de vuestro interés. Este es el primer artículo de los tres que voy a escribir sobre este curso, en las próximas publicaciones compartiré el manual de primeros actuantes y la directriz básica, no te los pierdas!
