System of Fear: A Dose of Radiation Reality

14 10 2013

In line with last week’s post, please see the below infographic, which paints radiation doses in the visual context of a sort of system of planets according to size (click to enlarge):


As is plainly evident, it’s shocking how much the public perception of radiation doses and negative health effects differs from reality.

(For example, in today’s perceptual climate, who would believe that a person could live within a mile of a nuclear powerplant for a thousand years before receiving the radiation dose from a single medical CT scan?)

If feedback to this is positive, I think I’ll make this the first in a series of similar infographics.  (Perhaps people would find it interesting/useful to next have illustrated the relative magnitudes of nuclear disasters?)


If anyone doubts the numbers in the above diagram, please feel free to investigate the references for yourselves!

Chinese satellite makes a move

11 11 2010

According to a story reported yesterday by the Associated Press, China has demonstrated nimble maneuvering of its satellites in orbit, a feat few other nations have been able to achieve.

The rendezvous between two of its orbiting craft, which occurred on August 19 and was not declared by China but was instead observed by international tracking stations, has set off alarm in some circles.  This capability must be employed by China in order to successfully launch and dock with their future proposed space laboratories, yet it may also double as the ability to intercept and sabotage enemy satellites and spacecraft.

Regardless of the potential military applications, the certain reality is that China’s space program is moving ahead at a determined pace.  This demonstration of their growing space capabilities is another reinforcement of just how serious they are about becoming a player in the future utilization of space.
