Final thoughts on Lynas Gebeng now that the TOL will be issued

Even after the PSC report giving the all clear for the Lynas Gebeng to be given a Temporary Operating License, it seems that the Anti Lynas folks who are probably anti anything that the BN Federal Gomen does has still not given up judging by this report:

Rules broken during Lynas protest, police say:

What's with the black coffin folks, nobody is going to die from radiation at Gebeng lah. 

I think the Himpunan Hijau/Stop Lynas/DAP/PKR/PAS dan sewaktu dengan mereka, should face the undeniable scientific fact that the Lynas Gebeng Plant is safe, its really time to move on and let Lynas Gebeng operate without let and hindrance and finally contribute to our economy and the nation's wealth. Heck, I do not even see PKR MP Fuziah amongst the crowd, do you?.... and last I heard she was missing from the Parliament session when the PSC gave their report even.

This will be my ultimate post on Lynas Gebeng, no further post is necessary now that the Gomen has finally convinced itself that the rare earth processing plant is safe and that it promises to monitor the plant tightly after being spooked by opposition politicians.

Lastly I would like to share this comment by my friend Dr. Looi on:

What is the "safe" level of radiation?

Public dose limits for exposure from uranium mining or nuclear plants are usually set at 1 mSv per year above background.

The figures below are given by the National Council on Radiation Protection and Measurement (NCRP) and its international counterpart, the International Commission on Radiological Protection (ICRP). Both of these organizations offer recommendations for the maximum permissible dose (MPD) of radiation.

General Public annual MPD by both NCRP and ICRP is 1 mSv.

For Radiation Workers, the annual MPD is 50 mSv (NCRP) and 20 mSv (ICRP), with a cumulative MPD of 10 mSv x Age.
MPD during pregnancy is 5 mSv (NCRP) and 2 mSv (ICRP).
This is over and above background exposure, and excludes medical exposure.

However, experts including Professor Wade Allison of Oxford University argue that the dose limit can safely be raised to 100 millisieverts, based on current health statistics.

Compare this with the dose of 0.002 millisieverts/year of exposure for people living within 1 km of the Lynas plant in the worst case scenario (estimated by Lynas).

This level of 0.002 mSv/yr is actually grossly overestimated because the low energy gamma rays from the Thorium-232 decay chain is able to travel less than 300 metres in air.

Note, the average energy of most abundant emission is only 0.059 MeV, though the gamma ray from Thallium-208 decay to stable Lead-208 has a higher energy of 2.62 MeV.

The radon-220 has a very short half life of only 55 seconds and as such cannot travel far and do not accumulate in confined spaces like the radon-222 from the Uranium decay series.

So the actual radiation dose at a distance greater than 300 metres from the plant is approaching 0 mSv/year !

Comparative Dosages in Biological Effect in mSv.

Dose from natural radiation in the human body: 0.40 mSv per year

Sleeping next to someone for 8 hours 0.02 mSv/yr (10x Lynas worst case)

Sleeping in wooden house = 0.20 mSv/yr (100x Lynas worst case)

Smoking a pack of cigarettes daily 0.20 mSv/yr (100x Lynas worst case)
Slag brick and granite house = up to 2.0 mSv/yr (1,000x Lynas worst case)

Chest X-ray = 0.10 mSv

Medical or dental X-ray 0.39 mSv

CT Scan (Chest) = 10 mSv

CT Fluoroscopy of abdomen and pelvis 6 to 90 mSv (median=31 mSv)
Average individual background radiation dose: 2 mSv per year (1.5 mSv per year for Australians and 3.0 mSv per year for Americans)

Dose from atmospheric sources (mostly radon): 2 mSv per year

Total average radiation dose for Americans: 6.2 mSv per year

Current average dose limit for nuclear workers: 20 mSv per year

Dose from background radiation in parts of Iran, India and Europe: 50 mSv per year
(Source: UNSCEAR and EPA and IAEA)

All the potassium that we eat everyday in our food contains potassium-40 and the normal dietary potassium would give a total of about 80 Bq per day.
Compare this with the Lynas waste which produces only 6 Bq/gm

Even your wife or husband is radioactive, with a radioactivity of 4,000 Bq from Potassium-40 and another 3,000 Bq from Carbon-14 giving a total of about 7,000 Bq!

Sleeping next to someone (i.e. your wife or husband) for 8 hours a day will lead to an exposure of 0.02 mSv/year (Source: UNSCEAR and EPA).

Since all living cells contain potassium, all types of meat, flesh, fruits, nuts and vegetables are radioactive because of the potassium-40 content.

The so-called sodium free salt recommended by health experts to combat high blood pressure is nothing more than just highly radioactive potassium salt! Even a lot of doctors, specialists and professors do not know this!

The message here is that more radioactive substances are freely sold in the shops and used as a fertilizer or eaten by us than you would otherwise thought.

Dr Looi

Thank you Dr. Looi!

I guess no matter whatever scientific evidence is presented to the Anti Lynas folks, nothing will change their view which is sadly set in political concrete, too much and too long exposure to unrealistic fear mongering does have an effect to ones perception. 

Thank God that our  anti Lynas brethren whose views are so myopically politicised that its not about lynas gebeng anymore, but its about painting a negative picture of the ruling BN Gomen, are in the small minority. Yup, they even have to join forces with the rioters of Bersih 3 to get maximum exposure for their cause.

Dr. Joyce Lee 李枂洙博士 @dr_joycelee (Twitter) A strong AntiLynas supporter due to her concerns on Radiation..

Her Tweet.. Learn to eat healthy at Wellness Educational Restaurant - dishes serves are ...

Really ?? Dr. Joyce Lee supports this Wellness center ? It promotes the use of Rock Salt which has Uranium and Plutonium in it !!!!

From their own website:
Learn to eat healthy at Wellness Educational Restaurant - dishes serves are without meat, cooked with ultraviolet filtered water, organic brown sugar, Himalaya Rock Salt, brown rice and olive oil.

What is Rock Salt ?​general80/salt.htm
Widely marketed, seemingly as an MLM operation, 'Original Himalayan Crystal Salt Elements' lists only the following data on their sites:

100% Pure - Contains 84 "natural" elements needed by the body: hydrogen, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluoride, sodium, magnesium, aluminum, silicum, phosphorus, sulfur, chloride, calcium, scandium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, gallium, germanium, arsenic, selenium, bromine, rubidium, strontium, yttrium, zirconium, niobium, molybdenum, ruthenium, rhodium palladium, silver, cadmium, indium, tin, antimony, tellurium, iodine, cesium, barium, lanthanum, cerium, praseodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, hafnium, tantalum, tungsten, rhenium, osmium, iridium, platinum, gold, mercury, thallium, lead, bismuth, polonium, astatine, francium, radium, actinium, thorium, protactinium, URANIUM, neptunium and PLUTONIUM.

They do not, however, provide a chemical analysis report for their product.
