Mercury mass measurement in fluorescent lamps via neutron activation analysis
Original language description
Not all fluorescent lamps are recycled, resulting in contamination of the environment with toxic mercury, making measurement of the mercury mass used in fluorescent lamps important. Mercury mass measurement of lamps via instrumental neutron activation analysis (NAA) was tested under various conditions in the LVR-15 research reactor. Fluorescent lamps were irradiated in different positions in vertical irradiation channels and a horizontal channel in neutron fields with total fluence rates from 3 x 10(8)cm(-2) s(-1) to 10(14) cm(-2) s(-1). The Hg-202(n,gamma)Hg-203 nuclear reaction was used for mercury mass evaluation. Activities of Hg-203 and others induced radio-nuclides were measured via gamma spectrometry with an HPGe detector at various times afterirradiation. Standards containing an Hg2Cl2 compound were used to determine mercury mass. Problems arise from the presence of elements with a large effective cross section in luminescent material (europium, antimony and gadolinium) and g
