Aim of study (acc. to author)
An international follow-up study was initiated to investigate the association between exposure to extremely low-frequency magnetic fields and survival from childhood acute lymphoblastic leukemia. The pooled analysis was based on data from following studies carried out in Canada (McBride et al., 1999), Denmark (Olsen et al., 1993), Germany (Michaelis et al., 1998 ), New Zealand (Dockerty et al., 1999), Sweden (Feychting et al., 1993), UK (UK Childhood Cancer Study Investigators, 1999), USA (Linet et al., 1997), Germany (Schüz et al., 2001), Japan (Kabuto et al., 2006), and USA (Foliart et al., 2006),
Further details
Endpoint/type of risk estimation
Exposure
Assessment
- measurement: long-term measurements (24 h or longer)
- calculation: based on historical power load information of power lines and their distance to nearby residences
