between radiation doses absorbed by
health care workers and dose area
product meter (DAP) measurements
at Universitas Hospital, Bloemfontein.
The DAP is an instrument which
accurately measures the radiation
emitted from the source. The study
included the interventional radiologists,
radiographers and nurses associated
with radiological intervention
procedures during the period
1 August 2003 - 31 August 2003. The
amount of radiation produced during
every procedure was measured by a
dose area product meter (DAP) and
routinely recorded. The absorbed
doses received by health care workers
were measured using a thermoluminescent
dose meter (TLD). The TLDs
were analysed and recorded at the end
of each week. Health care workers
wore TLDs on the following areas:
forehead, thyroid (attached under
thyroid guard), and abdomen (worn
under lead jacket). A strong positive
correlation (r = 0.9, p = 0.0374) was
found between the radiographers'
head TLD and DAP meter readings.
All other correlations between TLD
and DAP readings were not statistically
significant. Strong positive correlations
were found between the TLD
readings of the radiologists' and nurses'
bodies, the nurses' and radiographers'
bodies and the radiologists' and
the radiographers' bodies, all of which
were statistically significant.Read More
