Radiation safety is no longer the province of radiation safety professionals. It used to be, and they still control much of the infrastructure that defines the process – scientists and technicians who specialize in the esoterica of radiation safety, designers and manufacturers of the equipment that is used, administrators who write the procedures and set the standards, regulators who make the rules from their offices, bureaucrats who grade readiness and performance based on play-acting.
I don’t mean to offend any of you, but it is simply not the real thing. There is no way to simulate the panic and chaos of a dirty bomb or nuclear device. A review of events such as Hurricane Katrina demonstrates that, just like in war, plans don’t survive the first volley. People don’t show up, equipment isn’t where it’s supposed to be, training is forgotten, who’s in charge?
The people whose cells are being ionized, the people who will actually wear the protective clothing, hold the instruments, use the tools, and do the tasks, are the same people who drive your kid’s school bus, dig the trench for the new sewer system, fix the transformer that blew during the electrical storm. They are all professionals. They just aren’t professional radiation workers.
When the dirty bomb goes off, when the terrorist weapon detonates, when whatever radiological accident or attack occurs, they’ll have about 30 minutes to become one. Not 30 minutes from when the event happens. Those 30 minutes, and many more after them, will still be the province of the radiation safety professionals.
The 30 minutes I’m talking about start when these new professionals park their bus at the scene to pick up evacuees, when their backhoe is driven off the flatbed truck and made ready to move rubble, when the electric utility truck arrives and all those downed wires have to be re-connected. In those 30 minutes, these new professionals have to learn everything they need to know to do their job in a hazardous new environment, and the hazard is invisible.
Here’s an example. What units of measure should the emergency worker’s radiation monitor read in? Should it be REM, or Roentgens; or Sieverts, or rads, or Grays; should it have multiple ranges, like a low range and a mid-range and an high range; should it be analog or digital or flashing LED’s?
Here’s my answer – who cares? There is only one unit of measure that these new professional radiation workers understand or care about – risk. Instruments should read out in percentage increase of contracting cancer, because that’s what’s important to them.
I know the reply some will have, and that is we need to know and record and analyze radiation readings in units that are scientifically meaningful and let the managers make and implement suitable plans. Well, that ‘s what computers are for. Let them convert the 0 – 10 scale on the bus driver’s dosimeter into a dose equivalent man. All the bus driver wants to know is that 1 is fine, and 10 means if you don’t leave now, they’ll be looking for your body in an hour.
That’s the 30-Minute Professional. This side on the rope is clean, that side is dirty. Leave everything dirty on that side. This is your dosimeter. Wear it always. When you hear the alarm or see the LED flash, leave. This is your radiation meter. When the needle leaves green and moves to yellow, you should be doing something very important if you’re going to stay there. When it moves to red, leave. Drag the wounded if you can, but leave or you’ll be one of them.
The radiation safety professionals don’t get this yet. They’re still trying to take the instruments and procedures and mind-set of the professional radiation safety worker and dumb it down for the new draftees.
It won’t work.
Start fresh.
