Tau kah anda..?? 1. Tanpa ada PLTN di Indonesia kita sudah mandi radiasi tiap hari..dari lingkungan, ruang angkasa. Radioactive material is found throughout nature. It occurs naturally in the soil, rocks, water, air, and vegetation. The Earth, and all living things on it, are constantly bombarded by radiation from outer space. Natural background radiation comes from two primary sources: cosmic radiation and terrestrial sources. The worldwide average background dose for a human being is about 2.4 millisievert (mSv) per year.This exposure is mostly from cosmic radiation and natural radionuclides in the environment (including those within the body) 2. Angka paparan radiasi tsb jauh lebih tinggi ketimbang paparan akibat pengaruh kecelakaan PLTN maupun test senjata nuklir yang pernah dilakukan. This is far greater than human-caused background radiation exposure, which in the year 2000 amounted to an average of about 5 μSv per year from historical nuclear weapons testing, nuclear power accidents and nuclear industry operation combined, and is greater than the average exposure from medical tests, which ranges from 0.04 to 1 mSv per year. 3. PLTU berbahan bakar BATUBARA sebagai salah satu penyumbang radioaktivitas terbesar Older coal-fired power plants without effective fly ash capture are one of the largest sources of human-caused background radiation exposure. 4. Tubuh manusia juga mengandung radiasi lho.. Some of the essential elements that make up the human body, mainly potassium and carbon, have radioactive isotopes that add significantly to our background radiation dose. An average human contains about 30 milligrams of potassium-40 (40K) and about 10 nanograms (10−8 g) of carbon-14 (14C), which has a decay half-life of 5,730±40 years.
