RADIATION SAFETY







Radiation is categorized into two like Ionizing Radiation & Non-ionizing Radiation.

Radiation exposures is one of the serious health hazards to the employees.

Ionizing Radiation - Electromagnetic radiation and/or electrically charged or neutral particles which will interact with gases, liquids, or solids to produce ions. Examples include x-rays, gamma rays, protons, neutrons, and alpha particles.

 

Non-ionizing Radiation - Electromagnetic radiation with insufficient energy to produce ionization of atoms. Non-ionizing radiation energy usually is transformed into heat. Examples include microwaves, television and radio waves, visible light, infrared and ultraviolet radiation, and laser radiation.

Radiation safety guidelines

The below listed radiation safety guidelines will be adhered to by employees when the potential for exposure to ionizing and/or non-ionizing radiation exists.

1. On site procedures.

a. Evaluate the work site radiation safety procedure and program, if available, and Emergency Action or Preparedness Plan, where applicable.

b. Identify & communicate all known potential sources of radiation and assess the hazards using site-supplied data as well as measurements obtained by employees.

c. If it has been determined that there are potentially harmful radiation sources, contact the respective department for sampling procedures and appropriate self-monitoring equipment (TLD badges, neutron badges, other surveying instrumentation, etc.) for determining the personal exposure levels of employees.

d. Appraise work site hazard controls for effectiveness and take required actions.


Health Hazards of Chemicals


e. Determine the best means of minimizing exposure to the radiation hazard using source shielding and distance as the primary methods of protection. Limiting the duration of exposure will only be employed as a last resort for controlling a radiation hazard to which employees may be exposed, and even then, only with the consent of the responsible Manager(s). Employees will avoid direct exposure to the “beam” of radiation emitted by a source. Provide the necessary training to the required employees.

f. As Class 3b and 4 lasers can pose a serious hazard to the eyes, determine the type of eye protection to use wherever engineering controls are not feasible or where there is a likelihood of exposure to the beam. Make all employees aware of this and provide signages.

g. Seek support from the Health Response Team, through the responsible Manager(s), for additional technical assistance

2. Appropriate Personal Protective Equipment (PPE) use determination.

a. Review the employer’s radiation safety program and PPE requirements, including the PPE hazard assessment. Display the PPE Matrix.

b. Determine appropriate PPE and personal monitoring needed, based on the source and type of radiation.

c. Select and use appropriate PPE (shielding, equipment, work clothing) to minimize radiation exposure. If such equipment is not available at the work site or at the office, then the responsible Manager(s) will be immediately consulted before taking any action that may present further exposure to radiation.
