Module 2 Biological Effects 
Instructor's Notes 
The estimates in Table 2-2 indicate that the health risks 
from occupational radiation doses are smaller than the 
risks associated with normal day-to-day activities that 
we have grown to accept. 
b. 
Acceptance of a risk: 
1) 
is a personal matter. 
2) 
requires a good deal of informed judgment. 
c. 
The risks associated with occupational radiation doses 
are generally considered acceptable as compared to 
other occupational risks by most scientific groups who 
have studied them. There are some scientific groups 
who claim that the risk is too high. DOE continues to 
fund and review worker health studies to address these 
concerns. 
III. 
SUMMARY 
In summary, the estimated risk associated with occupation 
radiation dose is similar to other routine occupational risks and 
much less than some risks widely accepted in society. The risk of 
work in a radiation environment is considered within the normal 
occupational risk tolerance by national and international scientific 
groups. However, acceptance of risk is an individual matter and is 
best made with accurate information. A radiological worker should 
understand the risk of working in a nuclear environment in relation 
to the risks of daily life and the risks presented by work in other 
professions. The intent of this module is to give you the facts about 
radiation exposure risks and provide you with an opportunity to ask 
questions about radiation risk. It is hoped that understanding 
radiation risk and risk in general will help you to develop an 
informed and healthy respect for radiation, and that your 
understanding will eliminate excessive fear of or indifference to 
radiation.
