Distance between exposed object and exposure source
The rats were placed in holding units consisting of ventilated 5.1 cm x 15.2 cm PVC tubes fitted with 0.59-liter clear plastic bottle tops on one end and common 7.6-cm bolts with nuts at the other end. As the rats grew larger, new units were made using 8.9-cm PVC tubes, 1-liter bottles, and 10.2-cm bolts with nuts.
Each cell phone was positioned 1 cm from the head of the rats, at equal distances between two rats in holding chambers.
A sham exposure was conducted.
Rats were exposed for 3 hours, followed by a 30-minute rest period outside of the tubes and a second exposure for 3 more hours per day.
