FAQ’S : RADIATION THREAT CONCERNS
Is there is threat of health effects of radiation to the Malaysia community
* Currently there is no indication of any environmental radiation affecting Malaysia. Radiation related health effects depend on the exposure which in turn is dependent on the weather conditions such as wind and rain, as well as the distance from the source of radiation. The Atomic Energy Licensing Board (Ministry of Science, Technology and Innovation) is closely monitoring environmental levels of radioactive particles in Malaysia.
* Radiation dust can travel via wind but with Malaysia being 5,000km away, any radioactive material would be diluted by the time it arrives. Even the Japanese have only urged citizens within a 30km radius to evacuate the area.
What is ionizing radiation
* The disintegration of certain atoms release a type of energy known an Ionizing Radiation which can travel as electromagnetic waves or as particles. These atoms are called radionuclides.
What type of radiation exposure occurs in a nuclear plant
* A nuclear plant that is damaged may emit radionuclides such as Caesium and Radioactive Iodine.
How can people be exposed to ionizing radiation
* Exposure may occur externally or internally (breathing or swallowing radioactive material)
What are the health effects of radiation exposure
* Effects are felt only once the threshold dose is exceeded.
* Acute effects may include skin redness, hair loss, radiation burns and Acute radiation Syndrome
* Chronic exposure to radiation increases the risk of cancer
How can I protect myself
* Keep up to date on information given by the various ministries regarding the environmental situation
* Follow the advisories issued by the various ministries
Do I need potassium iodide tablets
* Potassium iodide tablets are given to saturate the thyroid and prevent the uptake of radioactive iodine by the thyroid gland. This may reduce the risk of cancer.
* Currently there is no need to take potassium iodide tablets as the risk of possible exposure is very small. The Ministry of health will provide an advisory if the need arises to take such precautions.
