#Lynas : Penduduk Lebih Sihat & Umur Panjang @fuziah99

Saya membaca artikel ini berulang kali di dalam dada akbar The Sun keluaran 7 Mac 2012 yang lepas. Bagi mempastikan samada artikel tersebut benar ataupun tidak, sekali lagi saya mencarinya melalui blog dan website The Sun.


Ada beberapa perkara fakta yang menarik dibawakan dalam ruang surat pembaca akbar The Sun. Jom baca kejap.

Belum pun Lynas beroperasi sepenuhnya, sudah ada Mutant di Kuantan

POTASSIUM tablets your doctor gives you for high blood pressure are highly radioactive with a radioactivity of 32 Bq/gm and we need about 2-3gm of potassium a day to stay alive.

The radioactivity comes from potassium-40. This is more than five times the radioactivity of the Lynas waste which contains only 6 Bq/gm mainly from Thorium-232.

All the potassium that we eat daily contains potassium-40 and the normal dietary potassium would give a total of about 80 Bq a day. The so-called sodium free salt recommended by health experts to combat high blood pressure is nothing more than highly radioactive potassium salt.

Thorium-232 decay produces only alpha particles which can be stopped by a piece of thin paper and cannot penetrate even the outer layer of the skin, whereas potassium-40 in our diet produces highly dangerous gamma and beta rays from all the three types of beta decay, ie electron emission, electron capture and positron emission.

The longer the half-life of a substance the less radioactive it is. Thorium-232 found in the Lynas waste has an incredibly long half-life of 14 billion years and as such is much less radioactive than the potassium-40 whose half-life is only 1.25 billion years.

Below is a comparison of radioactivity in Bq (number of atoms decaying in 1 second).
» Pure thorium-232 = 4,080 Bq/gm
» Pure potassium-40 = 254,000 Bq/gm
» Naturally occurring potassium = 31.825 Bq/gm
» Lynas rare earth waste = 6 Bq/gm

It has been estimated that in the worst case scenario, the radiation risk from the Lynas plant is only 0.002 mSv/yr.

In Ramsar, Iran, the naturally occurring radiation is extremely high at 260 mSv/yr. This is 13,000,000% higher than the expected worse case scenario in Kuantan. And the people in Ramsar have been found to be healthier and live longer than Iranians in other parts of the country. There is also no increase in the number of cancer cases.

We are exposed to radiation all our lives. We get 4,400 Bq of radiation from the potassium-40 with a further 3,000 Bq from carbon-14 which forms part of our body tissues.

There is no way we can escape from radiation. Even outer space is full of radiation.

Ulasan :

Cerita di Iran tu memang menarik. Kadar radiasinya tinggi 13,000,000% berbanding di Lynas, Kuantan. Tetapi penduduk di kawasan yang dikenali Ramsar tersebut mempunyai kesihatan yang baik dan jangka hayat hidup yang panjang berbanding orang² dari seluruh Iran. Juga tiada pertambahan jumlah pesakit kanser di sana.

So amacam Fuziah, ada beran?
