Potassium Concentration in Bone of Beijing Residents

Lin Lianqing(Beijing Public Health and Anti-epidemic Institute,100013)  
This paper presents the measuring results of K concentration in bone ash samplesof 65 residents in Beijing area by atomic absorption spectrum. The results indicate that the Kconcentrations in bone ash is logarrithmic normal distribution,ranging level is 0.75-8.44g/kg ash,the average and standard deviation is respectively 2.40 and 1.52 g/kg ash. Thehighest concentration (4.88 g/kg ash)appears in infentile stage (1 y),the lowerst con-centration(1.59 g/kg ash)appears in young stage(2-5y). The lower concentration(1.88g/kg ash)appears in adolescence(11-20 y). The K concentration in wet bone as a percent-age of weight is 0.067%. The specific activities of K-40 in bone is about 22 mBq/g wetbone. The total radiactivity of K-40 in whole bone is 220 Bq.The annual absorbed dose isreceived in adult bone from K-40 is estimated to be 95μGy.
