In Oklahoma, radiation workers are allowed to receive the following occupational exposures without limiting the activities of the workers. Ordinarily, the radiation dose limit for a worker is 5 rem (50 millisieverts) in a year. Radiation therapy involves exposure to hazardous radioactive particles, but has been used to safely treat cancer for more than 100 years. Do You Qualify? The amount of radiation that you will be allowed to receive will decrease because there is a lower dose limit for the embryo/fetus of female workers who have formally declared their pregnancy in writing. "The walls of the X-ray room have lead in them to make sure the radiation doesn't escape," Frey says.
