[ RadSafe ] Is this the beginning of the end of the debate on low-dose radiation effects?

[Otto G. Raabe]

9 July 2014

The important contrast is between a single instantaneous
radiation exposure and protracted exposure over time.

A very small instantaneous exposure will have a meaninglessly
small promotion effect on ongoing cancer advancement
even if it is not zero.

In sharp contrast, a protracted exposure at low dose rates
can interfere with ongoing "natural" cancer processes,

See my Figure 16 in Health Phys. 98:515-536; 2010
where I show a statistically significant reduction (zero cases)
in bone sarcoma from Sr+Y-90 protracted radiation exposures
for cumulative doses smaller than 10 Sv. This I call
a life-span virtual threshold for radiation induced cancer.

If you do not have this paper I will send it to you
