     The Radiological Health Handbook (1970) does not indicate that the 
     below decay schemes occur.
     
     For Pb-210, the genetic relationship states, "not parent Bi-210m, lim 
     10E-4% (LevyHB54)".
     
     For Po-212m, the principle means of production are stated as 
     Bi-209(a,p) and Pb-208(B-11, Li-7).

Radsafers,
Does anyone know if the following metastable-state daughters ever result from 
these naturally radioactive decay schemes?
     
Pb-210 (b-,g) Bi-210m 
Bi-212 (b-,g) Po-212m
     
The databases I'm using illustrate that the ground state daughters exist, but 
the metastables are left out in both cases.  Any insight will be appreciated, 
thanks!
