(Regulation on protection against hazards by X-

ray, of 8

th

 January 1987, Article 5 [Operation of 

X-ray emission source], clauses 1 to 4) 

a)  A licence is required by those who operate an 

X-ray emission source. 

b)  A licence in accordance with clause 1 is not 

required by those who operate an X-ray 
emission source on which the electron 
acceleration voltage does not exceed 20kV if 

1)  the local dose rate at a dista nce of 0,1m from 

the surface does not exceed 1µSv / h and  

2)  it is adequately indicated on the X-ray 

emission source that 
i) X-rays are generated and  
ii) the electron acceleration voltage must not 
exceed the maximum value stipulated by the 
manufacturer or importer. 

c)  A licence in accordance with Clause 1 is also            

not required by persons who operate an X -ray 
emission source on which the electron 
acceleration voltage exceeds 20kV if 

1)  the X -ray emission source has been granted 

a type approval and 

2)   it is adequately indicated on the X-ray 

emission source that 
i) X-rays are generated 
ii) the device stipulated by the manufacturer 
or importer guarantees that the maximum 
permissible local dose rate in accordance 
with the type approval is not exceeded and  
iii) the electron acceleration voltage must not 
exceed the maximum value stipulated by the 
manufacturer or importer. 

d)  Furthermore, a licence in accordance with 

Clause 1 is also not required by persons who 
operate X -ray emission sources on which the 
electron acceleration voltage does not exceed 
30kV if  

1)  the X -rays are generated only by intrinsically 

safe CRTs complying with Enclosure III, No. 
6, 

2)  the values stipulated in accordance with 

Enclosure III, No. 6.2 are limited by technical 
measures and specified in the device and  

3)  it is adequately indicated on the X-ray 

emission source that the X -rays generated 
are adequately screened by the intrinsically 
safe CRT.  

The unit does not emit X-ray radiation.
