I'm an EE major and I kind of want to go into a job where my skills can be used to make this country safer against terrorism. I understand that the risk of terrorism is small, but the consequences of a chemical, biological, or radiological strike would be unspeakable. I want to prevent such nightmarish scenarios. So what could I do for a career? I mentioned sensing. Would that be a good career choice? Developing sensors that can pick up on gamma rays or use spectroscopy to detect harmful chemicals before they're released sounds pretty good. I especially want to work to prevent nuclear terrorism. So what could an EE major do? What technologies are being developed? What about airborne or space-based sensor systems?
