Occupational exposure to radiation in medical practice in Ghana has been analysed for a 10-y period between 2000 and 2009. Monitored dose data in the medical institution in Ghana from the Radiation Protection Institute's database were extracted and analysed in terms of three categories: diagnostic radiology, radiotherapy and nuclear medicine. One hundred(More)
The immunoactive steroid dexamethasone (DXM) was administered to rats injected with a dose of phenylhydrazine (PHZ) known to induce anemia. PHZ treatment alone resulted in a hemolytic anemia that was most pronounced on Days 1-7 after injection. This anemia was accompanied by a leukocytosis that was greatest on Days 2-7 following PHZ treatment. Lymphocytes(More)
Rats were administered a single injection of phenylhydrazine (PHZ) which induced an hemolytic anemia that reached maximal levels two to four days following injection. This was accompanied by a leukocytosis which was most pronounced four to six days after injection; lymphocytes and monocytes accounted for 75 percent to 80 percent of the leukocyte count,(More)
Rats were injected with phenylhydrazine (PHZ) for periods of up to 6 months, during which time a marked leukocytosis was induced. The highest leukocyte counts occurred within 4-5 days following injection. An initial injection of 4 mg/100 gm body weight evoked a mean total leukocyte count of 129 X 10(3) cells/microliter. Successive weekly injections of 2(More)
A (60)Co radiotherapy source with an initial activity of 185 TBq has exhausted its useful half-life and has been replaced with a 222 TBq (60)Co source at the Korle-Bu Teaching Hospital; a radiological assessment was performed to ascertain the shielding integrity of the facility. Dose rate at selected critical positions were calculated for the old and new(More)
Institutions in the education, research and industrial sectors in Ghana are quite few in comparison to the medical sector. Occupational exposure to radiation in the education, research and industrial sectors in Ghana have been analysed for a 10 y period between 2000 and 2009, by extracting dose data from the database of the Radiation Protection Institute,(More)
