Application of Ionizing Radiations in daily life, its Hazards and Means of Protection

Application of Ionizing Radiations in daily life, its Hazards and Means of Protection

Ionizing radiation is a type of energy released by atoms in the form of electromagnetic waves or particles. People are exposed to natural sources of ionizing radiation, such as cosmic, radon,  etc., as well as man-made sources, such as x-rays and radioactive sources used in medicine, industries, etc. Ionizing radiation has many beneficial applications in medicine, industry, agriculture and research. As the use of ionizing radiation is increasing, so there is a possibility of health hazards if radiation are not properly used or contained. Acute health effects such as skin burns or acute radiation syndrome can occur when doses of radiation exceed certain levels, which are called Deterministic Effects. Low doses of ionizing radiation can increase the risk of longer term effects such as cancer, which are called Stochastic Effects. This risk of radiation can be minimized by following the radiation safety principles and some relevant safety instructions. This lecture, describes the sources of ionizing radiation, possible hazards and precautionary measures for protecting radiation workers, public and environment from harmful effects of ionizing radiations.

On March 19, 2019 at 11:00 am Mr Seraj munir  and Mr Asad Ejaz Goraya, Principal Scientific Officers from Pakistan Nuclear Radiation Authority (PNRA) visited CUIAbbottabad for a special lecture on “Application of Ionizing Radiations in Everyday Life and Radiation Hazards”.

Main Contents of Lecture:

  • Introduction to PNRA and Its Role in Ensuring Radiation Safety
  • Understanding the Radiation
  • Sources of Ionizing Radiation (Natural & Man-made)
  • Application of Radiation in Every Day Life
  • Benefits Vs Hazards
  • Protection from Ionizing Radiation
  • Safety Instructions to Follow in Daily Life

Introduction of Presenter:

Asad Ejaz Goraya, Principal Scientific Officer

Mr. Asad Ejaz Goraya did M.Sc Physics from Punjab University, Lahore in 2000. He got M.S  in Medical Physics in 2003 from PIEAS, Islamabad. He Joined Pakistan Nuclear Regulatory Authority (PNRA) in 2003. Mr Asad served three years at Regional Nuclear Safety Directorate –III, Karachi (2003-2006) and involved in licensing & inspections activities of radiation facilities like Radiotherapy, Nuclear Medicine, Radiology, Industrial Radiography, Nuclear Gauges, Research & Education etc. Then he served five years at Regional Nuclear Safety Directorate –II, Chashma (2006-2011) and worked as Resident Inspector at C-1 & C-2 Nuclear Power Plants. Mainly involved in activities like Radioactive Waste management, Radiation Protection, Environment Monitoring, Emergency Planning & Preparedness, Quality Assurance, Physical Protection, Transportation of fuel etc. He is also providing technical Support to National Institutes and International Atomic Energy Agency (IAEA) as an Expert in "Radiation Protection and Safety". Currently, he is working at National Institute of Safety and Security, PNRA HQ. Islamabad as a Principal Scientific Officer.

The session was conducted successfully. The speaker highlighted various aspects of the Radiation Protection and safety. He also highlighted the myths and beliefs about radiations. The students participated in a question and answer session. The session concluded with a vote of thanks and a meeting with the Director CUI Abbottabad, where the guests were presented with campus souvenirs as well.

This is a constant feature of PNRA Public engagement program PNRA requested to hold such awareness session at CUI Abbottabad in future to appraise more students on the subject and highlight it as a public health and environment issue and efforts of PNRA to ensure nuclear/radiation safety in the country.
