Lot of peoples have expressed concern over radiation levels in the wake of the deadly earthquake and consequent tsunami that struck Japan on March 11. This report is intended to provide a basic background on radiation risk, so that constituents can make more informed decisions regarding the well-being of their employees still within Japan and the region. The final page of the report includes a reference chart for radiation levels derived from Environmental Protection Agency and Nuclear Regulatory Commission guidelines.

Radiation Concerns
There are two main concerns that come from a potential exposure to radiation. The first is the short term effects of exposure to very high levels of radiation. The second is the long-term effects of exposure.

Acute Radiation Sickness usually develops from immediate exposure to high amounts of radiation and could cause a variety of health effects, ranging from nausea to death. Radiation levels consistent with Acute Radiation Sickness are usually observed at or near ground zero of a major radiation release. The effects of radiation in the short term can be found in the chart below.
Long-term, repeated exposure to radioactive materials may eventually lead to some disease, approximately 5-20 years after exposure. According to the United States Nuclear Regulatory Commission (NRC)

Pakcik rasa pakcik perlu kongsi maklumat penting ini demi keselamatan manusia sejagat. Ia mungkin juga berguna sebagai rujukan anak cucu pakcik bila Malaysia membina loji nuclear mereka sendiri.
2 memba kita komen:
lama tak dengar cerita ceritu dari pakcik, tiba-tiba keluar cerita menakutkan pasal radiasi. Namun ia satu maklumat yang berguna dan boleh digunakan sebagai panduan. apa khabar pakcik?
Tapi saya rasa rakyat kat malaysia ni terutama ahli politik dah lama terdedah kepada radiasi berkilo-dos banyaknya sebab ramai yang kepalanya dah tak betul. Betul ke pakcik?
Hi Dr Sam,
im good. how are you? Pakcik didnot expect anyone to comment on this entry pasal dah berzaman tak update. Hahaha
Pasal politik tu malas dah nak komen. Jauh di sudut hati pakcik dah merasakan pakcik sudah terlambat untuk diselamatkan :(
