US Govt. DOE 835.206 Radiation Limits For Embryo Or Fetus; Is .OO5 Sv, .5 rem or 5 mSv/Yr

Dr. Helen Caldicott MD talks about the nuclear bomb testing fallout effects on embryos and fetuses, (via very low dose radiation effects) as well as adults in the video above.  These negative health effects continue on today, and will continue for hundreds of thousands of years into the future, according to this medical expert. 

She is predicting epidemics of disease and deaths continuing on into the future of radiation induced diseases, genetic diseases, birth deformities, and cancers, all thanks due to the nuclear age and the peaceful use of the atom, and nothing else. She calls the atomic age random premeditated genetic engineering, via a forced medical experiment that no one agreed to. 

The following video gives visual evidence of the casualties of the nuclear fallout from Chernobyl. 

Fukushima and Chernobyl ‘accidental’ radiation releases are on top of the epidemics of disease and death that she is predicting, and just makes the epidemic that much worse. 

The problem with (govt/military) plutonium and most other radiation studies is that they did not seem to focus on children, fetuses or embryos. According to Dr Caldicott, children are 20 times (to 2,000 times for fetus) more sensitive to radiation than adults, just for uranium. This makes all of the studies on adults worthless, because none of the adult studies can be applied to children or babies, much less a fetus or an egg/sperm, and the studies do not cover the effects of plutonium on the above either.

A low dose of radiation can and does cause harm via the Petkau Effect. Petkau did an an experiment with very weak radiation and found that just 0.7 rads delivered in 11½ hours (1 millirad/min = 0.61 mSv/h) ruptured a cell membrane. This was counter to the prevailing assumption of a linear relationship between total dose or dose rate and the consequences.[3] What dose of radiation (lower than this) does it take to just damage a sperm or egg, (not kill it) thus causing a DNA break or damage, which then results in a deformed child or a genetic disease?

“Considering the fact that immature, undifferentiated and rapidly dividing cells are highly sensitive to radiation, it is not surprising that embryonic and fetal tissues are readily damaged by relatively low doses of radiation. It has been shown in experiments with mice that deleterious effects may be produced with doses of only 10 rads delivered to the embryo during the period of organogenesis.”

For gamma, x-ray and beta, the multiplication factor is 1, one rad equals one rem and one Gray equals one Sievert.‎

According to the US government regulation, the following are the maximum ‘safe’ doses for a fetus or embryo: 

835.206 Limits for the embryo/fetus.(a) The equivalent dose limit for the embryo/fetus from the period of conception to birth, as a result of occupational exposure of a declared pregnant worker, is 0.5 rem (0.005 Sv).(b) Substantial variation above a uniform exposure rate that would satisfy the limits provided in § 835.206(a) shall be avoided.(c) If the equivalent dose to the embryo/fetus is determined to have already exceeded 0.5 rem (0.005 Sv) by the time a worker declares her pregnancy, the declared pregnant worker shall not be assigned to tasks where additional occupational exposure is likely during the remaining gestation period.[58 FR 65485, Dec. 14, 1993, as amended at 72 FR 31926, June 8, 2007]
§ 835.207 Occupational dose limits for minors.The dose limits for minors occupationally exposed to radiation and/or radioactive materials at a DOE activity are 0.1 rem (0.001 Sv) total effective dose in a year and 10 percent of the occupational dose limits specified at § 835.202(a)(3) and (a)(4).

According to Wikipedia; “The rem and millirem are CGS units in widest use among the American public, industry, and government.[3] SI units are the norm outside of the US, and they are increasingly encountered within the US in academic, scientific, and engineering environments. The SI unit of dose equivalent is the sievert (Sv); conversion is straightforward, as 1 Sv = 100 rem by definition:
100.0000 rem = 100000.0 mrem = 1 Sv = 1.000000 Sv = 1000.000 mSv = 1000000 µSv
1.0000 rem = 1000.0 mrem = 1 rem = 0.010000 Sv = 10.000 mSv = 10000 µSv
0.1000 rem = 100.0 mrem = 1 mSv = 0.001000 Sv = 1.000 mSv = 1000 µSv
0.0010 rem = 1.0 mrem = 1 mrem = 0.000010 Sv = 0.010 mSv = 10 µSv
0.0001 rem = 0.1 mrem = 1 µSv = 0.000001 Sv = 0.001 mSv = 1 µSv

The conventional units for dose rate is mrem/h. Regulatory limits and chronic doses are often given in units of mrem/yr or rem/yr, where they are understood to represent the total amount of radiation allowed (or received) over the entire year. In many occupational scenarios, the hourly dose rate might fluctuate to levels thousands of times higher for a brief period of time, without infringing on the annual total exposure limits. 

There is no exact conversion from hours to years because of leap years, but approximate conversions are:1 mrem/h = 8766 mrem/yr0.1141 mrem/h = 1000 mrem/yr

The ICRP once adopted fixed conversion for occupational exposure, although these have not appeared in recent documents:[4]8 h = 1 day40 h = 1 week50 week = 1 yr

Therefore, for occupation exposures of that time period,1 mrem/h = 2000 mrem/yr x 0.5 mrem/h = 1000 mrem/yr” 


Violating this maximum ‘safe’ radiation exposure means that someone should be held accountable, according to Section 830.5. Civil and criminal penalties can be applied to all those responsible for violating this maximum dose to fetuses and children.

In the video above, the casualty rate of infants in the US is discussed, as a direct result of invisible, uncontrolled Fukushima radiation releases. The expert above estimates an additional 17,000 babies were killed, while the study below estimates an additional 50,000 deaths of newborns, just in the 3 months following Fukushima.

Fukushima Caused An Additional 50,000 USA Newborn Deaths 3/11 to 12/11; via @AGreenRoad

Where did these casualties come from, if the ‘official’ pro nuclear estimates and charts show that no deaths should have happened, because the radiation doses were too low to cause any deaths or health problems in anyone? 

The problem with the above ‘official’ charts and tables is that none of them apply to hot particles next to an egg, sperm or a fetus in the first two weeks of pregnancy. All of the studies focus on fetuses older than this. Fetuses older than two weeks are less sensitive to radiation due to cells dividing less rapidly. No studies have been done on ‘hot’ particles affecting eggs or sperm, and no studies have been done on very young fetuses, under 2 weeks of age.  “Irradiation may produce true genetic mutations in the immature germ cells of the fetus for which no threshold dose has been established.”

In the one study done on moms who received an XRay (external radiation only) of the lower abdomen (thus exposing only the eggs and not the sperm before conception), it appears that there was a statistically significant increase in leukemia risk among children whose mothers had received diagnostic x-rays during this period.

There is a huge difference between an alpha particle outside the body, an X-Ray, and a ‘hot’ alpha plutonium particle right next to or inside of a fertilized cell or set of cells. Go to minute 35 in the following podcast to listen to Arnie Gunderson explain how a ‘hot’ particle affects cells around it.

Weighting factors WR (formerly termed Q factor)
used to calculate equivalent dose
according to ICRP report 92[1]
Radiation Energy wR (also Q)

2 MeV – 20 MeV 10
> 20 MeV 5
protons, charged pions > 2 MeV 2
alpha particlesnuclear fission products,
heavy nuclei

Thus, for example, a given amount of energy absorbed in the form of 15 keV neutrons should be assumed to produce 10 times the damage caused by an equal amount of energy absorbed as X-rays or gamma rays.

Nuclear experts also deny or ignore the ‘weighting’ factor’, which means that external radiation such as an Xray is much less harmful than internal radiation from an alpha particle for example. As the chart shows above, the weighting factor for an alpha particle is 20 times that of an X-ray, dose for dose. 

Now add on top of that 20 times worse factor for a hot plutonium alpha radiation particle, the fact that the sperm or egg is right next to the plutonium particle or maybe even has it inside of itself, when it gets fertilized and divides rapidly. What do you think this intense 20 times more dangerous than an X-ray for an extremely rapidly dividing cell means? We still have not even touched the heavy metal toxicity and mutagenic quality of the plutonium, and this is added on top of that DNA alpha radiation breaking effect.

Bottom line, what all of this this means, is that the ‘official’ computer calculations by the ‘experts’ showing no deaths or injuries caused by low dose radiation are completely bogus and flawed, because they are based on flawed and bogus assumptions which are then fed into computers, which spit out bad estimates. Garbage in = garbage out.

The government chart and nuclear expert estimates DO NOT apply to the mom before conception, or to early stage pregnancy, or to egg/sperm cells exposed to a a ‘hot’ plutonium particle right next to them, for example, nor do they study the effect of plutonium on eggs, sperm or the fetus specifically. Plutonium is considered much more toxic than uranium, because it has never existed before on Earth and is entirely man made. There are no studies about this specifically.

X-rays by comparison to plutonium, uranium, strontium, iodine, xenon or any other man made element are completely harmless, because they pass through the body and do not stay. These various 100 plus radioactive elements coming out of a nuclear accident and then going into the egg, sperm or pre two week old fetus are orders of magnitude more dangerous; that is where the 50,000 deaths come from. Why is this so hard to understand among the pro nuclear industry folks? Why do the ‘experts’ keep insisting no one died, and no one will die from Fukushima, when the statistics and body count show the exact opposite, despite all of the coverups? 

Some experts estimate that the effect of a hot radioactive particle such as plutonium located right next to or inside of a sperm, egg, or on a pre 2 week old fetus may be up to 2 million times more dangerous than the equivalent radiation dose to a healthy adult male. Would you estimate any different risk when combining the risks of plutonium high energy alpha radiation AND heavy metal toxicity, inside or next to a cell such as an egg, sperm or just fertilized egg? 

Quotes From Famous People About Nuclear Energy And Low Dose Radiation Dangers; via @AGreenRoad

Bottom line, according to the above quoted nuclear experts, medical doctors and other scientists, there is no safe dose of radiation, and all radiation dosages are cumulative. The pro nuclear experts can argue all they want about how ‘safe’ nuclear power is, but people keep on dying from even the ‘natural’ radioactive elements such as radon and thorium, which humans have been exposed to for millions of years. 

How much more toxic and dangerous is plutonium on a cellular level, when humans have never seen it before in human history? Could it be that the effect of plutonium is much like diseases brought over by ‘settlers’ on American Indians? Those diseases were never seen before, and in most areas, up to 90% or more of those Indians exposed to those diseases died. We will all get to see what happens, because billions of people got exposed to nano hot particles of plutonium from Fukushima, and breathed them in.
