Cervical spinal cord injury is a highly morbid condition frequently associated with cardiovascular instability. This instability may include bradyarrhythmias, as well as hypotension, and usually resolves in a relatively short time. However, over a 3-year period (January 2003–December, 2005), 5 of 30 patients with complete cervical spinal cord injuries seen at our Level I trauma center required placement of permanent cardiac pacemakers for recurrent bradycardia/asystolic events. Strong consideration for pacemaker placement should be given for those spinal cord-injured patients with symptomatic bradyarrhythmic events still occurring 2 weeks after injury.

This paper presents measurement and evaluation of radiation power density emitted from mobile cellular base stations in Abuja and it’s environ. Forty (40) mobile base stations with ten (10) each from AIRTEL, ETISALAT, GLO and MTN located in areas with high population were randomly examined across Abuja. Broadband analysis method was employed in the measurement of the radiation power density. The results obtained shows that most of the base stations recorded lower radiation power density below the safety standard value of 4.5watt/m2 , 22.5 watt/m2 for 900MHz frequency though few base stations recorded above standard value: GLO-BS02, GLO-BS03 and MTN-BS02 recorded 59.02 mW/m2, 39.76 mW/m2 and 46.70 mW/m2 respectively. The result also revealed that as distance increases, the mean power density reduces. This is to said that human exposure to radio frequency radiation have less or no health hazard at distance far away from the mobile cellular base station.
