CETEC’s qualified and experienced scientists conduct a range of radiation assessments including:

  • Measurement and assessment of electromagnetic radiation from mobile phone towers
  • Assessment of RF radiation in offices
  • Assessment and decontamination  of nuclear medicine facilities
  • Assessment and decontamination of university laboratories
  • Radioactive waste assessments   

CETEC's NSW EPA licensed radiation professionals are experienced in conducting radiation surveys, electromagnetic radiation assessments, plus radiation contamination risk assessment and management.

Please read more below or contact us to discuss your radiation risk requirements for your upcoming project or in your workplace or home.

Electromagnetic Radiation Assessments for Mobile Phone Towers

Architects or builders may require an assessment prior to construction.  This is often the case for facilities with higher risk occupants, including for child care centres.  

A typical assessment includes:

  • Site inspection by licensed radiation professional
  • Measurement in the range of 3kHz to 300 GHz for:
    • Electric field strength
    • Magenetic field strength
    • Power flux density
  • Risk assessment report and recommendations

Radiation Assessments and Decontamination

At hospitals, research facilities and universities CETEC conducts radiation assessments and decontamination involving:

  • Assessing radioactive surface contamination at the site using direct (Handheld Geiger-Muller/Scintillation Detectors) and indirect (smear testing) evaluation methods
  • Visually assessing any other radiation hazards; i.e. equipment containing sealed radiation sources, radioactive chemicals stored and radioactive equipment
  • Management and occupational hygiene for the decontamination of radioactive contamination identified

Read more about Radiation

Radiation refers to the process in which energy is emitted as particles or electromagnetic waves through a medium or space. Radiation is commonly divided into 2 categories; non-ionising radiation and ionising radiation.

Non-ionising radiation generally refers to radiation at the lower energy end of the spectrum e.g. radio waves, microwaves, infrared and visible light. The use of non-ionising radiation is common in all work places and the home due to the widespread use of radio frequencies (RF) transmission devices such as mobile phones or common appliances such as microwave ovens.  

Ionising radiation refers to radiation with sufficient energy to cause chemical changes to materials that are subjected to it, including human tissue. The three main types of ionising radiation are as follows:

  • Alpha particles: made up of 2 protons and 2 neutrons (or in other words the nucleus of a helium atom)
  • Beta particles: made up of electrons
  • Gamma rays and x-rays: which are electromagnetic waves

The use of ionising radiation is common in medicine, education and industrial sectors with the many radioactive substances and devices.  Due to the inherent risk of exposure to some types of radiation it is important to properly manage radiation risk in the workplace.
