"Worker's Compensation" joke

A truck driver who had been delivering radioactive waste for the local reactor begins to feel sick after a few years on the job. He decided to seek compensation for his ailment.

Upon his arrival at the workers' compensation department, he is interviewed by an assessor.

Assessor: I see you work with radio-active materials and wish to claim compensation.

Trucker: Yeah, I feel really sick.

Assessor: Alright then, Does your employer take measures to protect you from radiation poisoning?

Trucker: Yeah, he gives me a lead suit to wear on the job.

Assessor: And what about the cabin in which you drive?

Trucker: Oh yeah. That's lead lined, all lead lined.

Assessor: What about the waste itself? Where is that kept?

Trucker: Oh, the stuff is held in a lead container, all lead.

Assessor: Let me see if I get this straight. You wear a lead suit, sit in a lead-lined cabin and the radio-active waste is kept in a lead container.

Trucker: Yeah, that's right. All lead.

Assessor: Then I can't see how you could claim against him for radiation poisoning.

Trucker: I'm not. I'm claiming for lead poisoning.
