Posted: Wed Mar 23, 2011 7:28 amI do not understand what this is showing me. What are those units (Bg/m^2) ? And what does this indicate about dosage or exposure risk?

British Gravitational System Mass
The British Gravitational System - BG
The British Gravitational System (Imperial System) of units is used by engineers in the English-speaking world with the same relation to the foot - pound - second system as the meter kilogram - force second system (SI) has to the meter - kilogram - second system. For engineers who deals with forces, instead of masses, it's convenient to use a system that has as its base units length, time, and force, instead of length, time and mass.
The three base units in the Imperial system are the foot, the second, and the pound-force.
In the BG system the mass unit is the slug and is defined from the Newton's Second Law (1). The unit of mass, the slug, is derived from the pound-force by defining it as the mass that will accelerate at 1 foot per second per second when a 1 pound-force acts upon it:
1 lb = (1 slug)(1 ft/s2)
In other words, 1 lb (pound) force acting on 1 slug mass will give the mass an acceleration of 1 ft/s2.
The weight of the mass from equation (2) in BG units can be expressed as:
w (lb) = m (slugs) g (ft/s2)
With a standard gravity - g = 32.17405 ft/s2 - the mass of 1 slug weights 32.17405 lbf (pound-force).

Effects of XE radiation plume - probably worse than our government is letting onto us.
Q: What about the radiation released? Is it dangerous?
A: It would appear that some of the nuclear fuel in FD1 has melted and released gaseous fission products to the interior of the reactor. These would include xenon, krypton, and iodine. There are about seven isotopes of xenon that are radioactive and would be released in such an incident, with atomic masses of 133, 135, 137, and 138, along with three isomers, 131m, 133m, and 135m. With the exception of the isomers, each of these xenon atoms will decay into cesium and some into other elements past cesium. There is also krypton but its radioactivity and decay products are of less concern.
Xenon itself is not particularly dangerous. It is a noble gas and is not concentrated in the body. Cesium is more of a concern. Here are the seven decay sequences:
Xenon-131m will decay to stable xenon-131.
Xenon-133m will decay to radioactive xenon-133.
Xenon-133 will decay to stable cesium-133.
Xenon-135m will decay to radioactive xenon-135.
Xenon-135 will decay to very mildly radioactive cesium-135.
Xenon-137 will decay to radioactive cesium-137.
Xenon-138 will decay to radioactive cesium-138 and then quickly to stable barium-138.
Of all of these, the decay of xenon-137 to cesium-137 is probably responsible for the most risk, but xenon-137 decays so quickly that the mobility of cesium-137 is limited. I do not think this poses much risk because it can’t get far. The xenon-135 has a longer half-life (9 hours) but decays to a nearly harmless form of cesium (135). I think this poses almost no risk due to the very long half life of cesium-135.
