Mill A, Frankenberg D, Bettega D, Hieber L, Saran A, Allen L, et al.
J Radiol Prot . 1998 Jul; 18(2):79-100. PMID: 9656189
For the assessment of radiation risk at low doses, it is presumed that the shape of the low-dose-response curve in humans for cancer induction is linear. Epidemiological data alone are...

Bettega D, Calzolari P, Marchesini R, Noris Chiorda G, Piazzolla A, Tallone L, et al.
Int J Radiat Biol . 1998 Apr; 73(3):303-9. PMID: 9525259
Purpose: To determine the RBE-LET relationship for C3H10T1/2 cell inactivation by protons in the LET range 11-33 keV/microm and to compare inactivation frequencies induced in C3H10T1/2 cells by protons and...

Bettega D, Calzolari P, Piazzolla A, Tallone L, Redpath J
Int J Radiat Biol . 1997 Nov; 72(5):523-9. PMID: 9374432
Survival and oncogenic transformation frequencies were determined through the cell cycle in hybrid cells (HeLa x human skin fibroblasts), exposed to 0.30 and 0.15 Gy 4.3 MeV (LET= 101 keV/microm)...

Bettega D, Calzolari P, Costa A, Chiorda G, Tallone L
Radiat Res . 1995 Jun; 142(3):276-80. PMID: 7761577
Oncogenic transformation of synchronized C3H 10T1/2 cells was determined after exposure to 4.3 MeV alpha particles (LET = 101 keV/microns). Two synchronization techniques were tested using basic and modified protocols:...

Durante M, Gialanella G, Grossi G, Nappo M, Pugliese M, Bettega D, et al.
Int J Radiat Biol . 1994 Apr; 65(4):437-47. PMID: 7908931
Cell-cycle stage radiosensitivity for the induction of chromosome aberrations has been investigated in C3H 10T1/2 cells. Exponentially growing cells were irradiated with 3 Gy X-rays (80 kVp) or 0.6 Gy...

Bettega D, Calzolari P, Chiorda G
Radiat Res . 1992 Jul; 131(1):66-71. PMID: 1626050
Oncogenic transformation of C3H 10T1/2 cells was determined after exposure to graded doses of 4.3-MeV alpha particles LET = 101 keV/microns. The source of alpha particles was 244Cm and the...

Bettega D, Calzolari P, Ottolenghi A, Tallone Lombardi L
Radiat Environ Biophys . 1991 Jan; 30(1):53-70. PMID: 2000445
Cell survival was studied by analyzing the inactivation probability density function and its fundamental parameters. Mean D, variance sigma 2 and mode Dmode were evaluated and a set of equations...

Bettega D, Calzolari P, Ottolenghi A, Rimoldi E, Tallone Lombardi L
Int J Radiat Biol . 1989 Dec; 56(6):989-98. PMID: 2574226
The effects of cell density on transformation frequencies were studied in C3H10T1/2 cells exposed to 0.5 and 7 Gy of 200 kVp X-rays. Initial cell density strongly influenced transformation frequency;...

Bettega D, Calzolari P, Ottolenghi A, Tallone Lombardi L
Int J Radiat Biol . 1989 Apr; 55(4):641-51. PMID: 2564873
Growth curves and size of the colonies of C3H10T1/2 cells exposed to low-LET radiation (31 MeV protons) were determined after 0, 1, 3, 5, and 7 Gy. The data show...
